CsPbX3 perovskite nanocrystal (NC) is considered as an excellent optical material and widely applied in optoelectronics. However, its poor water stability impedes study enzyme-like activity, further inhibits application biomimetic cascade catalysis. Herein, for the first time, oxidase-like ascorbate activities of amphiphilic polymer capped are demonstrated, catalytic mechanism explored. Furthermore, all-nanozyme system (multifunctional CsPbBr3 @Zr-metal organic framework (Zr-MOF) Prussian blue peroxidase-like nanozyme) constructed with a portable paper-based device realizing dual-mode (ratiometric fluorescence colorimetric) detection ascorbic acid point-of-care (POC) fashion. This report on utilization all-inorganic NC catalysis, which opens new avenue POC clinical disease diagnosis.

Noble metal catalysts excel in many applications due to their high chemical stability and unique plasmonic catalytic properties. However, noble metals the form of nanoparticles tend aggregate easily have costs, which limit actual applications. Developing with minimal usage optimal activity is urgently needed. Metal–organic frameworks (MOFs) are composed organic ligands ions/clusters via coordination bonds, inherently possess structural diversity, specific surface area, other important With rapid development MOFs MOF-based composite materials, they been used design synthesize nanostructures nanomaterials activity. The preparation, characterization, application materials combining attracted significant interest. Incorporation into MOF structures an effective method eliminate agglomeration problems instability MOFs. By utilization synergistic effects properties MOFs, exhibit enhanced performance over each component. This review focuses on synthesis strategies studies supported

With the global limited food resources receiving grievous damage from frequent climate changes and ascending demand resulting increasing population growth, perovskite nanocrystals with distinctive photoelectric properties have emerged as attractive prospective luminogens for exploitation of rapid, easy operation, low cost, highly accurate, excellently sensitive, good selective biosensors to detect foodborne hazards in practices. Perovskite demonstrated supreme advantages luminescent biosensing products due their high photoluminescence (PL) quantum yield, narrow full width at half-maximum PL, tunable PL entire visible spectrum, preparation, various modification strategies compared conventional semiconductors. Herein, we carried out a comprehensive discussion concerning application high-performance products, including brief introduction nanocrystals, nanocrystal-based biosensors, different categories products. Finally, challenges opportunities faced by superior were proposed promote practicality future supply.

The conventional lateral flow immunoassay (LFIA) method using colloidal gold nanoparticles (Au NPs) as labeling agents faces two inherent limitations, including restricted sensitivity and poor quantitative capability, which impede early viral infection detection. Herein, we designed synthesized CsPbBr3 perovskite quantum dot-based composite nanoparticles, CsPbBr3@SiO2@Fe3O4 (CSF), integrated fluorescence detection magnetic enrichment properties into LFIA technology achieved rapid, sensitive, convenient of the SARS-CoV-2 virus N protein. In this study, served a high-quantum-yield fluorescent signaling probe, while SiO2 significantly enhanced stability biomodifiability CsPbBr3. Importantly, shell shows relatively low absorption or scattering toward fluorescence, maintaining yield up to 74.4% in CsPbBr3@SiO2. Assembly Fe3O4 mediated by PEI further method's reduced matrix interference through enrichment. Consequently, range 1 × 102 5 106 pg·mL–1 after enrichment, with limit (LOD) 58.8 pg·mL–1, representing 13.3-fold improvement compared nonenriched samples (7.58 pg·mL–1) 2-orders-of-magnitude over commercial kits. Furthermore, exhibited 80% positive 100% negative rates clinical samples. This approach holds promise for on-site diagnosis, home-based tests, disease procession evaluation.

Water instability and sensing homogeneity are the Achilles' heel of CsPbX3 NPs in biological fluids application. This work reports preparation Mn2+:CsPbCl3@SiO2 yolk–shell nanoparticles (YSNPs) aqueous solutions created through integration ligand, surface, crystal engineering strategies. The SN2 reaction between 4-chlorobutyric acid (CBA) oleylamine (OAm) yields a zwitterionic ligand that facilitates dispersion YSNPs water, while robust SiO2 shell enhances their overall stability. Besides, Mn2+ doping not only introduces second emission center but also enables potential postsynthetic designability, leading to switching from MnO2@YSNPs with excellent oxidase (OXD)-like activity. Theoretical calculations reveal electron transfer CsPbCl3 situ MnO2 adsorption–desorption process 3,3′,5,5′-tetramethylbenzidine (TMB) synergistically amplify OXD-like In presence ascorbic (AA), Mn4+ (fluorescent nanozyme) is reduced dissociated, thereby inhibiting activity triggering fluorescence "turn-on/off", i.e., dual-mode recognition. Finally, biomarker reporting platform based on fluorescent nanozyme constructed AA as reporter molecule, accurate detection human serum alkaline phosphatase (ALP) realized, demonstrating vast perovskites biosensing.

High-quality thin-film composite (TFC) membranes with high selectivity and permeability have great significance owing to their practical applications, specifically for the accurate differentiation of monovalent divalent ions. However, trade-off effect between is still a big challenge due difficult structure adjustment selective layer. Herein, polydopamine (PDA) functionalized hydrophobic long alkane chain was first explored as functional amphiphilic interlayer synthesize high-quality TFC via confined interfacial polymerization (IP) reaction. The not only restricted formation polyamide (PA) matrix in pores substrate but also accelerated spatially more homogeneous formed PA active layer uniform pore size distribution. method may provide an effective principle construction versatile polyamide-based perm-selectivity on various supports. NaCl/Na2SO4 separation factor D-8/PA membrane reached 204.07, while flux increased up 25.71 L m–2 h–1 bar–1. This progress provides feasible way devisable creative industrial application.
