Among the several types of inorganic nanoparticles available,silica nanoparticles(SNP)have earned their relevance in biological applications namely,as bioimaging agents.In fact,uorescent SNP(FSNP)have been explored in this-eld as protective nanocarriers,overcoming some limitations presented by conventional organic dyes such as high photobleaching rates.A crucial aspect on the use of uorescent SNP relates to their surface properties,since it determines the extent of interaction between nanoparticles and biological systems,namely in terms of colloidal stability in water,cellular recognition and internalization,tracking,biodistribution and speci-city,among others.Therefore,it is imperative to understand the mechanisms underlying the interaction between biosystems and the SNP surfaces,making surface functionalization a relevant step in order to take full advantage of particle properties.The versatility of the surface chemistry on silica platforms,together with the intrinsic hydrophilicity and biocompatibility,make these systems suitable for bioimaging applications,such as those mentioned in this review. 展开更多

A generic method was described to change surface biocompatibihty by introducing reactive functional groups onto surfaces of polymeric substrates and covalently binding them with biomolecules.A block copolymer with protected carboxylic acid functionality,poly（styrene-b-tert-butyl acrylate）（PS-PtBA）,was spin coated from solutions in toluene on a bioinert polystyrene（PS） substrate to form a bilayer structure：a surface layer of the poly（tert-butyl acrylate）（PtBA） blocks that order at the air-polymer interface and a bottom layer of the PS blocks that entangle with the PS substrate.The thickness of the PtBA layer and the area density of tert-butyl ester groups of PtBA increased linearly with the concentration of the spin coating solution until a 2 nm saturated monolayer coverage of PtBA was achieved at the concentration of 0.4%W/W.The protected carboxylic acid groups were generated by exposing the tert-butyl ester groups of PtBA to trifluoroacetic acid （TFA） for bioconjugation with FMRF peptides via amide bonds.The yield of the bioconjugation reaction for the saturated surface was calculated to be 37.1%based on X-ray photoelectron spectroscopy（XPS） measurements.The success of each functionalization step was demonstrated and characterized by XPS and contact angle measurements.This polymer functionalization/modification concept can be virtually applied to any polymeric substrate by choosing appropriate functional block copolymers and biomolecules to attain novel biocompatibility. 展开更多

Affinity membranes are fabricated for boric acid removal by the surface functionalization of microporous polypropylene membrane(MPPM)with lactose-based polyols.The affinity is based on specific complexation between boric acid and saccharide polyols.A photoinduced grafting-chemical reaction sequence was used to prepare these affinity membranes.Poly(2-aminoethyl methacrylate hydrochloride)[poly(AEMA)]was grafted on the surfaces of MPPM by UV-induced graft polymerization.Grafting in the membrane pores was visualized by dying the cross-section of poly(AEMA)-grafted MPPM with fluorescein disodium and imaging with confocal laser scanning microscopy.It is concluded that lactose ligands can be covalently immobilized on the external surface and in the pores by the subsequent coupling of poly(AEMA)with lactobionic acid(LA).Physical and chemical properties of the affinity membranes were characterized by field emission scanning electron microscopy and Fourier Transform Infrared/Attenuated Total Refraction spectroscopy(FT-IR/ATR).3-Aminophenyl boric acid(3-APBA)was removed from aqueous solution by a single piece of lactose-functionalized MPPM in a dynamic filtration system.The results show that the 3-APBA removal reaches an optimal efficiency(39.5%)under the alkaline condition(pH9.1),which can be improved by increasing the immobilization density of LA.Regeneration of these affinity membranes can be easily realized through acid-base washing because the complexation of boric acid and saccharide polyol is reversible. 展开更多

Wetting condition of microanostructured surface has received tremendous attention due to the potential applications in commercial,industrial,and military areas.Surfaces with extreme wetting properties,e.g.,superhydrophobic or superhydrophilic,are extensively employed due to their superior anti-icing,drag reduction,enhanced boiling heat transfer,self-cleaning,and anti-bacterial properties depending on solid-liquid interfacial interactions.Laser-based techniques have gained popularity in recent years to create microano-structured surface owing to their high flexibility,system precision,and ease for automation.These techniques create laser induced periodic surface structures(LIPSS)or hierarchical structures on substrate material.However,microanostructures alone cannot attain the desired wettability.Subsequent modification of surface chemistry is essentially needed to achieve target extreme wettability.This review paper aims to provide a comprehensive review for both laser texturing techniques and the following chemistry modification methods.Recent research progress and fundamental mechanisms of surface structure generation via different types of lasers and various chemistry modification methods are discussed.The complex combination between the laser texturing and surface chemistry modification methods to decide the final wetting condition is presented.More importantly,surface functionalities of these surfaces with extreme wetting properties are discussed.Lastly,prospects for future research are proposed and discussed. 展开更多

Surface functionalization of sensor chip for probe immobilization is crucial for the biosensing applications of surface plasmon resonance(SPR)sensors.In this paper,we report a method circulating the dopamine aqueous solution to coat polydopamine film on sensing surface for surface functionalization of SPR chip.The polydopamine film with available thickness can be easily prepared by controlling the circulation time and the biorecognition elements can be immobilized on the polydopamine film for specific molecular interaction analysis.These opera-tions are all performed under flow condition in the fuidic system,and have the advantages of easy implementation,less time consuming,and low cost,because the reagents and devices used in the operations are routinely applied in most laboratories.In this study,the specific absorption between the protein A probe immobilized on the sensing surface and human immunoglobulin G in the buffer is monitored based on this surface functionalization strategy to demonstrated its feasibility for SPR biosensing applications. 展开更多

The development of sustainable energy storage technologies is critical in addressing the global challenges posed by climate change.Supercapacitors,while offering exceptional power density and cycling stability,suffer from relatively low energy density,limiting their widespread use in large-scale energy storage systems.To overcome this limitation,we designed a novel composite electrode material featuring a core–shell structure.The core derived from well-defined ZIF-67 nanocubes(NCs)was innovatively processed into a hollow structure,which enhanced ion diffusion and increased the overall energy storage capacity by reducing internal resistance.Meanwhile,the shell consisted of 3D hierarchical Ni–Co layered double hydroxides(NiCo-LDH)grown in situ employing an ambient-temperature method,offering high electrochemical activity and abundant active sites for efficient charge storage.The ultimately synthesized multi-scale hollow core–shell material,Co3O4-HNC@NiCo-LDH,integrated the respective merits of the shell and core materials,while simultaneously addressing issues that arise when these materials exist in isolation.It effectively mitigated problems such as volume expansion and agglomeration that materials might encounter during electrochemical reactions,thereby further enhancing the materials’performance and service life.Notably,in situ Raman spectroscopy was utilized to trace the dynamic redox processes and structural changes occurring during electrochemical cycling,thereby validating the stability and effectiveness of the charge storage mechanism.The resulting material,Co3O4-HNC@NiCo-LDH,demonstrated impressive capacitance(1862.4 F g−1at 2 A g−1),high energy density(76.8 Wh kg−1at 2 A g−1),and excellent cycling stability(98.38%after 15000 cycles at 15 A g−1),offering a promising solution for next-generation supercapacitors. 展开更多

This study presents a systematic methodology for producing multi-walled carbon nanotubes(MWCNTs)/Inconel 718 composite powder,especially for the Laser Directed Energy Deposition(LDED)process.This approach integrates mild oxidative functionalization of MWCNTs to reduce agglomerations and High-Energy Ball Milling(HEBM)to enhance dispersion over the Inconel 718 powder.The MWCNTs were functionalized through a two-step chemical treatment:(1)magnetic stirring in a 3:1 H2SO4and HNO3 solution,using two distinct acid concentrations(3 M and 8 M),followed by(2)an ultrasonic bath in H2O2solution.Structural defects were characterized using Raman spectroscopy(RS),thermogravimetric analysis(TGA),and transmission electron microscopy(TEM),while X-ray photoelectron spectroscopy(XPS)quantified the amount of oxygen-containing functional groups.Among the six functionalization processes,the treatment condition involving 4 h of magnetic stirring,then 2 h in the sonication bath,emerged as optimal,yielding a relatively high functional group attachment(11.47%)with lower surface defects and without compromising uniformity in mixing.The FESEM analysis of the functionalized MWCNTs(up to 2 wt%)/Inconel 718 composite powder,collected from the LDED machine bed,confirmed uniform dispersion,validating the functionalization strategy.Although developed for LDED,this strategy is also suitable for MMC production processes that use powder as feedstock. 展开更多

Nickel oxide(NiO)‐based electrodes with high theoretical specific capacitance can effectively increase the energy density of supercapacitors-the key factor limiting their practical deployment.However,several issues still restrict the production of advanced NiO‐based electrodes.First,a facile strategy to concurrently enhance surface‐interface and bulk conductivity is still absent,limiting the overall electrode conductivity.Second,strategies that boost OH−affinity often increase its desorption barrier,impeding OH−migration.Herein,to address these issues,heterostructured Ni/NiO porous nanoflowers with P‐doping sites and abundant surface PO43−groups(P‐PO4‐Ni/NiO)are prepared through simple phosphidation.In this material,(1)the heterojunction between Ni and P‐doped NiO increases the overall electrode conductivity;(2)surface PO43−groups and P‐doping sites synergistically boost the affinity for OH−and improve their transfer kinetics;and(3)owing to their structure,porous nanoflowers show a large electrolyte contact area.As a result,the specific capacitance of P‐PO4‐Ni/NiO is five times higher than that of pristine NiO.When assembled into asymmetric supercapacitors,the device exhibits an energy density of 33.1 Wh kg−1at 750 W kg−1.At−40℃,the device retains 62.0%of its room‐temperature capacitance and shows nearly no fade after 20,000 charge-discharge cycles.This work presents a robust route for the development of practical transition metal oxide‐based supercapacitors. 展开更多

Hafnium oxide(HfO2)nanoparticles(NPs),derived from a rare-metal element,have gained increasing attention as a versatile class of functional nanostructures with unique optical,dielectric,and surface properties that enable diverse biomedical applications.As a representative rare-metal oxide,HfO2 NPs with well-defined architectures offer advantageous features such as a high atomic number,chemical inertness,tunable morphology,biocompatibility,and exceptional stability for integration with other functional materials.Significant advances have been achieved in controlling crystalline phases,improving scalability,and tailoring optoelectronic and surface characteristics.However,their exploration in biomedical fields remains limited and fragmented.This review discusses the key principles of controlled synthesis,interfacial functionalization,and toxicity evaluation of HfO2 NPs.Emphasis is placed on their emerging biomedical applications,including bioimaging,radiosensitization,drug delivery,and multimodal theranostic integration.Attention is also given to hybrid systems combining HfO2 NPs with polymers,metal oxides,metal-organic frameworks,and two-dimensional nanomaterials,where interfacial synergies underpin enhanced therapeutic efficacy,diagnostic contrast,and safety.Finally,this review concludes with challenges,opportunities,and future directions,proposing strategies to establish reproducible,scalable,and high-performance rare-metal oxide platforms for nextgeneration biomedical and functional technologies.It aims to provide a comprehensive roadmap linking the synthesis,properties,and applications of HfO2 nanomaterials,positioning them as a model rare-metal oxide system to bridge the gap between nanomaterial design and clinical translation in nanomedicine. 展开更多

Biochar has emerged as a sustainable and cost-effective adsorbent for the removal of emerging contaminants from wastewater. This review critically explores recent advances in the design and application of engineered biochars derived from diverse waste biomasses, focusing on the link between structural modifications and pollutant-specific removal mechanisms. Functionalization strategies including physical and chemical activation, heteroatom doping, surface grafting, and hybrid composite formation are systematically analyzed for their impact on adsorption efficiency and selectivity toward dyes, heavy metals, pharmaceuticals, and per- and polyfluoroalkyl substances. Particular attention is paid to performance in column systems, regeneration potential, and behaviour in complex real-world matrices, which remain underexplored in current literature. The diversity of adsorption mechanisms such as electrostatic interactions, π–π stacking, hydrogen bonding, ion exchange, and surface complexation is discussed in relation to surface chemistry and pollutant type. Despite promising results, critical challenges persist, including biochar heterogeneity, lack of standard production protocols, potential leaching of dopants, and limitations in large-scale implementation. This review highlights the need for unified assessment frameworks, life cycle analyses, and integration strategies aligned with circular economy principles. By bridging the gap between laboratory innovation and field-scale application, this work provides a comprehensive roadmap for researchers, engineers, and stakeholders seeking to deploy next-generation biochar-based sorbents in sustainable water treatment systems. 展开更多

This study reports a polyethylene glycol(PEG)-assisted surface functionalization strategy to achieve colloidal stabilization of rod-shaped ZnO nanorods and their uniform integration into Lyocell fibers via dry-jet wet spinning.ZnO nanorods are prone to aggregation due to high surface energy,limiting their antibacterial efficacy.We demonstrate that PEG molecules adsorb onto ZnO surfaces through hydrogen bonding and coordination,providing steric stabilization that prevents agglomeration and ensures homogeneous dispersion in the spinning dope.The optimized composite fiber with 3 wt%ZnO exhibits balanced performance,delivering inhibition rates above 95%against Escherichia coli and Staphylococcus aureus,while retaining over 80%efficacy after 50 laundering cycles.Morphological and structural analyses confirm that PEG-mediated interfacial interactions facilitate stable nanoparticle encapsulation without disrupting the cellulose crystalline structure.Antibacterial mechanism studies further reveal that light-induced reactive oxygen species(ROS)generation is the dominant antibacterial pathway,while Zn2+release provides a secondary contribution.In addition,the antibacterial performance remains stable under different humidity conditions(30%-80%RH),indicating good environmental robustness.This work demonstrates a scalable and eco-friendly route to fabricate durable antibacterial fibers and highlights the broader significance of colloidal stabilization and interfacial engineering in functional polymer composites. 展开更多

Atomically precise metal-chalcogenide supertetrahedral clusters (MCSCs) are supposed to be more attractive for functionalization than conventional metal-sulfide quantum dots owing to their potential ability to establish precise structure-composition-property relationships.However,the accurate surface functionalization of such cluster-based species remains difficult.In this paper,we present a facile method for synthesizing discrete MCSCs decorated with different functional groups via a one-step solvothermal reaction,which was demonstrated to have better solvent dispersibility compared with ligand-free ones.In addition,the composites were also prepared by combining ligand-free clusters (or ligand-partially protected or amino-modified ones) with two-dimensional MXene nanosheets.The composites derived from amino-modified clusters exhibited optimal performance of photocatalytic hydrogen evolution.Furthermore,the hydrogen bonding interactions between modified amino groups and MXene nanosheets were verified by 1H-NMR spectroscopy.This work provides a facile approach for the surface functionalization of MCSCs,and facilitates the expansion of the functionality of atomically precise nano-species. 展开更多

BACKGROUND Dry eye disease(DED)is a multifactorial ocular surface disorder with rising prevalence.It is closely related to systemic health and psychological factors,such as sleep and mood disorders,which significantly impact the quality of life of patients.AIM To explore the correlations between ocular surface function,sleep quality,and anxiety/depression in patients with DED.METHODS This was a cross-sectional investigative study that included 358 patients with DED between January 2022 and January 2025.Ocular surface was assessed using the ocular surface disease index(OSDI),tear film break-up time,fluorescein staining score,and Schirmer I test.The Pittsburgh Sleep Quality Index(PSQI),Self-Rating Anxiety Scale(SAS),and Self-Rating Depression Scale(SDS)were used to evaluate sleep quality and anxiety/depression levels.Correlation and linear regression analyses were used to explore the relationships.RESULTS The mean PSQI score of the patients was 9.94±2.18;the mean SAS score was 47.30±4.90,and the mean SDS score was 50.08±5.52.These suggested a prevalence of sleep and psychological abnormalities.There was a significant correlation between the indicators of ocular surface function(OSDI,tear film break-up time,fluorescein staining,and Schirmer I test)and PSQI,SAS,and SDS scores(P<0.05).Moreover,multiple regression revealed that age≥50 years(β=1.55,P=0.029),PSQI scores(β=0.58,P<0.001),SAS scores(β=0.17,P=0.017),and SDS scores(β=0.15,P=0.019)were independent predictors of the OSDI scores.CONCLUSION Ocular surface function in patients with DED is closely related to sleep quality and anxiety/depression,emphasizing the need for holistic clinical management. 展开更多

Indium-based materials(e.g.,In2O3)are a class of promising non-noble metal-based catalysts for electroreduction of carbon dioxide(CO2).However,competitive hydrogen reduction reaction(HER)on indium-based catalysts hampers CO2 reduction reaction(CO2RR)process.We herein tune the interfacial microenvironment of In2O3 through chemical graft of alkyl phosphoric acid molecules using a facile solution-processed strategy for the first time,which is distinguished from other researches that tailor intrinsic activity of In2O3 themselves.The surface functionalization of alkyl phosphoric acids over In2O3 is demonstrated to remarkably boost CO2 conversion.For example,octadecylphosphonic acid modified In2O3 exhibits Faraday efficiency for H2 H2 H2(FE)of as low as 6.6%and FEHCOOH of 86.5%at-0.67 V vs.RHE,which are far superior to parent In2O3 counterparts(FE of 24.0%and FEHCOOH of 63.1%).Moreover,the enhancing effect of alkyl phosphoric acid functionalization is found to be closely related to the length of alkyl chains.By virtue of comprehensive experimental characterizations and molecular dynamics simulations,it is revealed that the modification of alkyl phosphoric acids significantly alters the interface microenvironment of the electrocatalyst,which changes the electrocatalyst surface from hydrophilic and aerophobic to hydrophobic and aerophilic.In this case,the water molecules are pushed away and more CO2 molecules are trapped,increasing local CO2 concentration at In2O3 active sites,thus leading to the significantly enhanced CO2RR and suppressed HER.This work highlights the importance of regulating the interfacial microenvironment of inorganic catalysts by molecular surface functionalization as a means for promoting the electrochemical performance in electrosynthesis and beyond. 展开更多

Graphene-like borophene was theoretically proposed and recently synthesized on Al(111)surface,however,how to conquer its structural instability is still an open question.By means of density functional theory computations,we theoretically predicted that honeycomb borophene can be well stabilized by double-sided surface passivation with monovalent functional groups(X=F,Cl,Br,I,OH,and NH2)due to the electron redistributions.The system undergoes the transition from metallic to semiconducting upon functionalization,while the energy gap depends on the choice of functional groups.Under external strain,the gap values can be manipulated over a broad range.Our further calculations indicated that the functionalized borophene possesses moderate and anisotropic carrier mobility,which is comparable to or even higher than some 2D materials such as MoS2 and phosphorene.Our work provides a feasible strategy to effectively stabilize the graphene-like borophene and tune the electronic properties with great potentials for electronic applications. 展开更多

Nanomedicine,which merges the realms of nanotechnology and medicine,presents transformative strategies for advancing healthcare through nanoscale manipulation of materials.Among these,metal–organic frameworks(MOFs),with a unique hybrid structure of metal ions interconnected by organic ligands,have emerged as a novel class of inorganic nanoparticles with significant potential in drug delivery systems(DDS).This review explores the innovative applications of MOFs in DDS,emphasizing their distinctive porous architectures that facilitate the adsorption and controlled release of therapeutic agents.The versatility of MOFs is further enhanced by surface functionalization,which not only augments their dispersibility and targeting efficiency but also addresses the biological barriers that traditionally impede nanoparticle-based drug delivery.These barriers include the adsorption of bioproteins,which can mask the nanoparticles and prompt immune recognition,and the complex interplay within the tumor microenvironment(TME),which affects nanoparticle penetration and efficacy.Additionally,the cell membrane prevents nanoparticles from being internalized into the cell,and drugs released within the cell are removed by efflux pumps,impeding their therapeutic effect.Through a comprehensive analysis,we highlighted the strategies employed to overcome these obstacles,leveraging the multifunctional capabilities of MOFs to enhance their therapeutic payload delivery and targeting precision. 展开更多
