Water pollution remediation has emerged as a paramount challenge amid rapid industry,agriculture and society development,particularly for persistent,low-concentration contaminants that evade conventional water treatments.Integrating photocatalysis with molecular imprinting technology offers a transformative approach for specific adsorption,enhanced matrix resistance,and efficient radical utilization through pollutant targeted degradation,delivering great potential in water pollution preferential remediation.This review briefly summarized the fundamental mechanisms underlying molecular imprinting and photocatalysis,and discussed in detail the research necessity and key scientific challenges faced by molecular imprinting photocatalysts(MIPCs).Combining different photocatalytic materials,synergistic mechanism of selective adsorption with photodegradation,and water pollution removal efficiency,the innovative design strategies of MIPCs are discussed in detail from perspective of molecular imprinting(photocatalyst and MIPs separated,photocatalyst serving as imprinted matrix)and photocatalysis(diverse photocatalysts,e.g.,TiO₂,g-C₃N₄,ZnO,CdS).Additionally,theoretical calculations about this field were analyzed critically.Finally,the key challenges and long-term prospects were outlined,emphasizing four critical dimensions:(1)enhancement of selective removal efficiency;(2)elucidation of reaction mechanisms;(3)scalability for practical applications;(4)innovative imprinting strategies.This review is expected to offer fundamental insights into both the scientific principles and engineering applications of MIPCs,while catalyzing advancements in water preferential remediation technologies. 展开更多

The preparation of porous molecularly imprinted polymers(MIPs)from starch,a natural product,presents significant challenges.In this study,we developed a straightforward method for preparing porous MIPs(DFP-MIPs)by crosslinking short amylose as a functional monomer with decafluorobiphenyl(DFP)as a cross-linker.Experimental results indicated that DFP-MIPs exhibited a larger specific surface area(14.06m2/g)and adsorption capacity(26.3 mg/g),and a high imprinting factor of 3.14 for estradiol(E2),compared to MIPs prepared using tetrafluorobenzenediamine with a single benzene ring as the cross-linker.A method for detecting E2 in milk and meat samples was also established using DFP-MIPs as the adsorbent in conjunction with high-performance liquid chromatography.Under optimal conditions,this method demonstrated a linear range of 0.0200–0.400μg/g,a detection limit of 0.00300μg/g,and a recovery rate of 85.2%to 101.4%.The proposed method for preparing DFP-MIPs is expected to provide a new pathway for the development of porous and highly selective MIPs using amylose. 展开更多

A Cr(Ⅵ)ion-imprinted covalent organic framework(IICOF)with a three-dimensional porous structure was developed at room temperature for the first time.The IICOF was then blended with polyvinylidene fluoride(PVDF)to synthesize a novel mixed matrix membrane for the selective removal of Cr(Ⅵ).The morphologies and properties of membranes with varying IICOF contents were characterized,demonstrating that the uniform distribution of positively charged IICOF within the membrane enhanced Cr(Ⅵ)adsorption.Increasing the IICOF content significantly improved Cr(Ⅵ)adsorption on the membrane,with the removal efficiency from 1.99%to 91.8%.The ion imprinting effect enabled the mixed matrix membrane to exhibit excellent selectivity for Cr(Ⅵ),even in the presence of 100-fold competing ion concentrations.Functional groups in the IICOF within the mixed matrix membrane provided the active sites with electrostatic attraction and hydrogen bonding,forming the primary driving forces for Cr(Ⅵ)adsorption.Under acidic conditions,the protonation of=N−and its conversion to=NH+−generated additional active sites and further enhanced adsorption.The study also identified a critical saturation point and corresponding critical initial concentration for Cr(Ⅵ)adsorption.Furthermore,the 10%-IICOF/PVDF membrane demonstrated excellent recyclability,indicating that it is a promising candidate for the selective and efficient removal of Cr(Ⅵ). 展开更多

Aiming at the selective adsorption removal and efficient separation of pollutant phenol from wastewater,a photo-responsive surface molecularly imprinted adsorbent with smart ultraviolet(UV)-switchable wettability has been designed and synthesized.The selective adsorption of phenol is achieved by constructing phenol-imprinted cavities with o-phenylenediamine(o-PD)as the functional monomer,while the reversible switching of surface wettability is realized through the synergistic effect of the photo-induced hydrophilic hollow titanium dioxide(H-TiO2)matrix and the cross-linked hydrophobic trimethylolpropane trimethacrylate imprinted polymer layer.The surface wettability of the constructed adsorbent o-PD/SMIP@H-TiO2can be changed from hydrophobic(water contact angle of 113°)to hydrophilic(water contact angle of 21°)after 30 min of UV irradiation,which is beneficial to the dispersion of the adsorbent and mass transfer of adsorbate.As the phenol adsorption takes place in the dark and reaches equilibrium(24.4 mg/g),the surface of o-PD/SMIP@H-TiO2gradually reverts to hydrophobicity,which facilitate the separation and regeneration of adsorbent,and the adsorption capacity in the 5th reuse maintains 94%.Furthermore,97%of the adsorbed phenol can be recovered from the saturated o-PD/SMIP@H-TiO2adsorbent.Meanwhile,the adsorbent demonstrates distinct specific recognition and selective adsorption performance towards phenol when multiple phenolic pollutants are present in the solution.The selectivity is attributed to the formation of hydrogen bonds between the nitrogen atoms on the directionally-arranged o-PD monomers within the imprinted cavities and the hydrogen atoms of phenol molecules.This photo-responsive imprinted adsorbent material is expected to exert a substantial influence on the wastewater purification industry. 展开更多

Exposure to different neonicotinoid insecticides(NNIs)can cause varying degrees of harm to mammals and may even be carcinogenic.Due to their similar molecular structures,it is not only difficult to distinguish NNIs in analysis,but also cross-reactions can also occur.These cross-reactions cause the calibration curves to exhibit strong nonlinearities that cannot be fitted by usual mathematical models.Here,we present an electrochemical sensor array comprising three sensing units for the simultaneous determination of imidacloprid,thiamethoxam,and nitenpyram.The method eliminates cross-reaction with the aid of machine learning.The machine learning model comprises three components:the Douglas-Peucker algorithm for data compression,principal component analysis for classification,and an artificial neural network for quantification.The randomly assigned validation set showed a classification accuracy of 96.3%for the model.The prediction accuracy was 98.77%.The limit of detection was<0.037μmol/L,with a detection range from 0.1μmol/L to 200μmol/L.Finally,the spiked tea samples were tested,and a satisfactory agreement was obtained between the expected and predicted values. 展开更多

To clarify the thermal evolution characteristics of organic matter in the ZizhongWeiyuan area in Sichuan Basin,solid bitumen reflectance of the Lower Cambrian Qiongzhusi Formation(QFm)shale was measured by Raman Spectroscopy(RS)method.Constrained by vitrinite reflectance(Ro)data,burial and thermal evolution histories of QFm shale were reconstructed through basin numerical simulation technology.The evolution model of and critical period of organic matter was determined,and its dominant drivers were analyzed.The results show that the asphalt Raman vitrinite reflectance(RmcRo)ranges from 3.21%to 4.15%.Thermal maturity within the trough follows a southern part>central part>northern part trend.Thermal maturity is moderate within the paleo-uplift,whereas organic matter outside the paleo-uplift has undergone graphitization.Two types of thermal evolution imprints were established:a continuous heating type and a stop heating type of Silurian–Permian.Sedimentary burial,paleogeomorphology,tectonic movement and Emeishan mantle plume are the dominant drivers of multi-stage thermal imprints of the QFm shale.The three factors are coupled with each other.The Late Caledonian and Late Indosinian are the key periods of organic matter thermal evolution.The Leshan-Longnüsi paleo-uplift weakens the thermal effect of the Permian Emeishan mantle plume.The current thermal evolution pattern of the QFm is mainly determined by the continuous subsidence of the Triassic–Cretaceous.Stop heating model of Silurian–Permian locks the maturity of organic matter in the gold window,thus controlling the enrichment of QFm shale gas.It provides new insights for shale gas migration,enrichment and effective exploration and development of shale gas in the Lower Paleozoic QFm. 展开更多

Background:Laminarin,aβ-1,3-glucan derived from brown algae,possesses various bioactive properties.However,its conventional purification process is laborious and technically challenging.This study aimed to develop a novel method for the rapid and selective extraction of laminarin from seaweeds using magnetic molecularly imprinted polymers(MIPs).Methods:The magnetic MIPs were synthesized in an aqueous medium via surface radical polymerization.The synthesis employed laminarin as the template molecule,water-soluble VBTAC(4-vinylbenzyltrimethylammonium chloride)as the functional monomer,and MBA(N,N’-methylenebisacrylamide)as the crosslinker.The adsorption behavior of the polymers was evaluated,and the data were fitted to kinetic and isotherm models.Results:The adsorption process of laminarin onto the MIPs was best described by the pseudo-second-order kinetic model and the Langmuir isotherm model.Under optimized conditions,the polymers achieved a maximum adsorption capacity of 204.08μg·mg-1 with an imprinting factor of 1.33.Conclusion:The synthesized magnetic molecularly imprinted polymers demonstrated the ability to selectively and efficiently adsorb laminarin in empirical trials,offering a promising alternative to conventional purification methods. 展开更多

The search for non-ergodic mechanisms in quantum many-body systems has become a frontier area of research in non-equilibrium physics.In this work,we introduce Hilbert subspace imprint(HSI)-a new mechanism that enables evasion of thermalization,standing as an independent non-ergodic mechanism alongside quantum many-body scars(QMBS)and Hilbert space fragmentation(HSF).HSI manifests when initial states overlap exclusively with a polynomial scaling(with system size)set of eigenstates.We demonstrate this phenomenon through two distinct approaches:weak symmetry breaking and initial state engineering.In the former case,we observe that ferromagnetic states including those with a single spin-flip display non-thermal behavior under weak U(1)breaking,while antiferromag-netic states thermalize.In contrast,the Z2-symmetric model shows thermalization for both ferromagnetic and antiferromagnetic states.In the latter case,we engineer the initial state prepared by shallow quantum circuits that enhance the overlap with the small target subspace. 展开更多

Molecularly imprinted polymers(MIPs)are a kind of synthetic receptors possessing wide application prospects in proteins recognition.However,there are still great challenges in proteins imprinting due to their large size and easy conformation change.In this study,we explored epitope-oriented MIP based on host-guest interaction(hg-MIP)and constructed a novel hg-MIP-SERS(surface-enhanced Raman scatting)approach for efficiently recognizing the terminal epitopes of neuron-specific enolase(NSE),a well-known disease biomarker for small cell lung cancer,neuroblstom,and Alzheimer's disease.The C-and N-terminal epitopes of NSE were modified with 4-(phenylazo)benzoic acid,then they were used as the templates and immobilized onβ-cyclodextrin-functionalized substrates.The imprinted layer was formed by polymerization of various functional monomers.Combined with SERS detection,an antibody-free sandwich assay based on hg-MIP was successfully used to detect the concentration of NSE in human serums,with the advantages of simple operation,small sample volume(5μL),wide linear range(1–104ng/m L)and a limit of detection as low as 0.01 ng/m L.The developed epitope-oriented hg-MIP-SERS approach can also be extended to other proteins,expanding the imprinting method of proteins,and has a broad development space in the field of protein separation and detection. 展开更多

Hypobaric hypoxia encountered at high altitudes impairs reproductive health and fertility across species.Previous findings have demonstrated that maternal hypoxia exposure disrupts granulosa cell(GC)viability and oocyte maturation in female offspring;however,its transgenerational impact on male reproductive outcomes remains poorly elucidated.In this study,pregnant mice(F0)were subjected to hypoxic conditions,and male progeny across four generations(F1-F4)were evaluated.Results revealed that maternal hypoxia induced mild alterations in sperm DNA methylation in F1 males but caused profound developmental defects in F2 embryos,predominantly affecting males.Following mating of F1males with control females,a substantial proportion of male F2 fetuses were lost at embryonic day(E)13.5,attributed to placental malformations.Integrated RNA sequencing and whole-genome bisulfite sequencing of placentas from male fetuses revealed aberrant expression of imprinted genes,including Gnas,Slc38a4,Jade1,and Kcnq1,which also exhibited differential methylation in F1sperm.These findings demonstrate that maternal hypoxia disrupts epigenetic programming in F1 germ cells,impairing placental development and fetal viability in F2males,thereby leading to an unbalanced sex ratio.Overall,this study elucidates the mechanisms by which environmental hypoxia influences sex ratios and offers critical insights into hypoxia-induced reproductive impairments in mammals. 展开更多

Quantitative determination of tetracycline(TC)in environment and foods is of great importance,as excessive residues might have negative effects on human health and environmental risks.Herein,a selfpowered molecularly imprinted photoelectrochemical(PEC)sensor based on the Zn O/C photoanode and the Fe-doped CuBi2O4(CBFO)photocathode is developed for the sensitive detection of TC.The photocathodic current can be amplified by the efficient electron transfer caused by the Fermi energy level gap between the photoanode and photocathode.Furthermore,molecularly imprinted polymers(MIPs)at photocathode can selectivity identify the TC templates and thus improve the specificity.Under the optimal conditions,the sensor has a linear range of 10-2-1.0×105 nmol/L,and a limit of detection(LOD)of 0.007 nmol/L(S/N=3).More crucially,the milk sample detection is carried out using the as-prepared sensor,and the outcome is satisfactory.The research gives us a novel sensing platform for quick and accurate antibiotic(like TC)in environment and food monitoring. 展开更多

Maize(Zea mays L.)is a globally significant crop essential for food,feed,and bioenergy production.The maize kernel,serving as a primary sink for starch,proteins,lipids,and essential micronutrients,is crucial for enhancing maize yield and quality.Previous studies have established the critical role of Polycomb Repressive Complex 2(PRC2)in regulating kernel development.In this study,we applied a reverse genetics approach to investigate the role of ZmFIE1,the homolog of the PRC2 complex component Extra sex combs(Esc),in maize development.The functional loss of ZmFIE1 significantly reduces embryo size in the early stage but has a relatively small impact on mature kernels.Integrating transcriptional and metabolomic profiling suggests that ZmFIE1 is involved in regulating nutrient balance between the endosperm and embryo.In addition,we demonstrate that ZmFIE1 is maternally expressed,and that the maternal inheritance of the fie1 allele significantly affects the imprinting status of paternally imprinted genes.Overall,our results suggest that ZmFIE1 is a key gene involved in the modulation of embryo development via regulating genomic imprinting and nutrient balance between embryo and endosperm,which provides new insights into the regulation mechanism underlying kernel development. 展开更多

This work develops a protein imprinted nanosphere with varied recognition specificity for bovine serum albumin(BSA)and lysozyme(Lyz)under different UV light through a gradient dual crosslinked imprinting strategy(i.e.,covalent crosslinking and dynamic reversible crosslinking).The imprinting cavities are initially constructed using irreversible covalent crosslinking to specifically recognize BSA,and then the coumarin residues in the imprinting cavities are crosslinked under 365 nm UV light to further imprint Lyz,because Lyz has smaller size than BSA.Since the photo-crosslinking of coumarin is a reversible reaction,the imprinting cavities of Lyz can be de-crosslinked under 254 nm UV light and restore the imprinting cavities of BSA.Moreover,the N-isopropyl acrylamide(NIPAM)and pyrrolidine residues copolymerized in the polymeric surface of the nanospheres are temperature-and p H-responsive respectively.Therefore,the protein rebinding and release behaviors of the nanospheres are controlled by external temperature and p H.As a result,the materials can selectively separate BSA from real bovine whole blood and Lyz from egg white under different UV light.This study may provide a new strategy for construction of protein imprinted materials with tunable specificity for different proteins. 展开更多

Phase imprinting enables the dynamic generation of superflow in bosonic atoms,effectively overcoming traditional limitations such as vortex number constraints and heating effects.However,the mechanisms underlying superflow formation remain insufficiently understood.In this work,we reveal these mechanisms by studying the time evolution of the transferred total angular momentum and the quantized current throughout the phase imprinting process,achieved through numerically solving the time-dependent Schrodinger and Gross-Pitaevskii equations.We demonstrate that the Bose gas dynamically acquires angular momentum through the density depletion induced by the phase imprinting potential,whereas quantized currents emerge from azimuthal phase slips accompanied by complete density depletions.Regarding the impact of system parameters,such as interactions,we find that interactions hinder superflow formation,as the azimuthal density distribution becomes less susceptible to the phase imprinting potential.Our findings offer microscopic insights into the dynamic development of superflow during the phase imprinting process and provide valuable guidance for ongoing experimental efforts. 展开更多

As a typical bioflavonoid,diosmetin is desirable in the field of natural medicine,healthy food,and cosmetics by anti-cancer,antibacterial,antioxidant,estrogen-like and anti-inflammatory activities,and it comes from a wide range of sources in traditional Chinese medicine like spider fragrance,spearmint and chrysanthemum,as well as in Citrus fruit.However,traditional analytical methods such as silica gel column chromatography face multiple challenges in the selective extraction of diosmetin from biological materials and traditional Chinese medicinal materials.Therefore,it is urgent to develop a new type of absorbent with high efficiency,recyclability and good specificity to diosmetin.In this investigation,a magnetic surface molecularly imprinted polymer(labeled as Diosmetin/SMIPs)was synthesized employing magnetic nanoparticles as the carrier and 4-vinylpyridinyl(4-VP)as the functional monomer by surface imprinting technology.The functional monomer was screened by the binding energy(△E)between functional monomers and template molecules via computational simulation.The Diosmetin/SMIPs had a high level of specific recognition and adsorption capability towards diosmetin with a 20.25 mg g-1 adsorption capacity and an imprinting factor(IF)of 2.28.Additionally,it demonstrated excellent regeneration performance with 8 adsorption/desorption cycles.In addition,91.20%-94.16% of spiked diosmetin was recovered from the lemon peel samples.The strategy of constructing Diosmetin/SMIPs based on computational simulation can effectively enhance the specific adsorption performance of diosmetin.Meanwhile,Diosmetin/SMIPs synthesized by imprinting polymerization showed excellent anti-interference and reusability,and realized efficient targeted extraction of diosmetin from lemon peel samples.The results of this investigation provide a promising adsorbent for selective enrichment of diosmetin from Citrus fruit and complicated materials. 展开更多

Bromocresol green(BCG)and malachite green(MG)are water-soluble toxic organic dyes with adverse health and environmental implications.This study presented a conjugate imprinted adsorbent(CIA)synthesized by incorporating trimethoprim vanillin ligand into a highly crosslinked polymer,designed for the efficient removal of BCG and MG from wastewater.Characterization of CIA involved X-ray powder diffraction,Fourier transform infrared,and scanning electron microscopic analyses.Batch adsorption processes were conducted to evaluate the adsorption characteristics of CIA,with focuses on the effects of contact time,initial dye concentration,pH,and temperature.The molecularly imprinted polymers(MIPs)achieved removal efficiencies of 99.27%and 98.99%at equilibrium for BCG and MG adsorption,respectively.The non-imprinted polymers(NIPs)demonstrated BCG and MG adsorption efficiencies of 51.52%and 62.90%at equilibrium,respectively.Kinetic and isotherm models were employed to elucidate the BCG and MG adsorption mechanisms.The thermodynamic results indicated non-spontaneous and spontaneous reactions for BCG and MG adsorption on MIPs under the examined temperature conditions.The adsorbent exhibited sustained high removal efficiency through five reuse cycles,with no apparent reduction in adsorption performance.Validation of the adsorbent using real textile wastewater samples achieved BCG and MG removal efficiencies of 85.5%-87.5%.The adsorbent outperformed previously reported materials in BCG and MG adsorption.The synthesized CIA is a promising adsorbent for BCG and MG dye removal,contributing to water sustainability. 展开更多

In this work,a novel electrochemical sensor based on covalent organic framework@carbon black@molecularly imprinted polydopamine(COF@CB@MPDA)was developed for selective recognition and determination of ciprofloxacin(CF).COF@CB@MPDA possessed good water dispersibility and was synthesized by the selfpolymerization of dopamine under alkaline conditions in the presence of the COF,CB and CF.The high surface area COF enhanced the adsorption of CF,whilst CB gave the composites high electrical conductivity to improve the sensitivity of the proposed COF@CB@MPDA/glassy carbon electrode(GCE)sensor.The specific recognition of CF by COF@CB@MPDA involved hydrogen bonding and van der Waals interactions.Under optimized conditions,the sensor showed a good linear relationship with CF concentration over the range of 5.0×10–7and 1.0×10–4mol/L,with a limit of detection(LOD)of 9.53×10–8mol/L.Further,the developed sensor exhibited high selectivity,repeatability and stability for CF detection in milk and milk powders.The method used to fabricate the COF@CB@MPDA/GCE sensor could be easily adapted for the selective recognition and detection of other antibacterial agents and organic pollutants in the environment. 展开更多

In this work,by combining the specific selectivity of molecularly imprinted polymer(MIP)with a simple and sensitive electrochemiluminescence(ECL)detection method,a molecularly imprinted ECL sensor for kanamycin(KA)was developed.The MIP film was synthesized on the surface of gold electrode via electrochemical polymerization,using pyrrole(PY)as the functional monomer and KA as the template molecule.The commonly used luminescent reagent Ru(bpy)32+was employed as the ECL probe,and its co-reagent tripropylamine(TPA)was added to enhance the detection sensitivity of the sensor.Quantitative analysis of KA was performed by evaluating the difference in ECL responses between MIP film electrodes after KA removal and KA rebinding.The sensor exhibited high selectivity,good reproducibility,and stability toward KA,with a linear range of 5.00×10-8 to 1.00×10-5 mol·L-1 and a limit of detection of 1.67×10-8 mol·L-1(S/N=3).This work would provide a new idea for the development of simple and sensitive molecularly imprinted ECL sensors. 展开更多

DEAR EDITOR,Genomic imprinting often results in parent-of-origin specific differential expression of maternally and paternally inherited alleles and plays an essential role in mammalian development and growth.Mammalian genomic imprinting has primarily been studied in mice and humans,with only limited information available for pigs.To systematically characterize this phenomenon and evaluate imprinting status between different species,we investigated imprinted genes on a genome-wide scale in pig brain tissues. 展开更多
