Metal-organic framework (MOF)-derived carbon materials are commonly used as sensing materials, but their limited accessibility to active sites and specific surface area restrict applications. In this study, we proposed a simple method involving facile tannic acid etching calcination create NiCo-embedded hollow N-doped nanocubes (NiCo@HNC) using MOFs sacrificial templates. The resulting NiCo@HNC material has large area, improved mass transport channels, enhanced exposure of electroactive due its unique structure high porosity, leading electrocatalytic activity. Moreover, with the utilization substrate dopamine functional monomer, ratiometric molecularly imprinted electrochemical sensor was developed for selective sensitive detection carbendazim (CBZ). This demonstrated wide linear range 0.0003-10 μM low limit 0.1 nM. addition, utilized accurate quantification CBZ in actual carrot/strawberry samples recovery 96.0-103.0%, indicating potential practical application.

In this study, we report a multiplexed platform for the simultaneous determination of five marine toxins. The proposed biosensor is based on disposable electrical printed (DEP) microarray composed eight individually addressable carbon electrodes. electrodeposition gold nanoparticles surface offers high conductivity and enlarges electroactive area. immobilization thiolated aptamers AuNP-decorated electrodes provides stable, well-orientated organized binary self-assembled monolayer sensitive accurate detection. A simple electrochemical aptasensor AuNPs was designed to synchronously detect multiple cyanotoxins, namely, microcystin-LR (MC-LR), Cylindrospermopsin (CYL), anatoxin-α, saxitoxin okadaic acid (OA). choice toxins their widespread presence toxicity aquatic ecosystems humans. Taking advantage conformational change upon target binding, cyanotoxin detection achieved by monitoring resulting electron transfer increase square-wave voltammetry. Under optimal conditions, linear range estimated be from 0.018 nM 200 all toxins, except MC-LR where possible within 0.073 150 nM. Excellent sensitivity with limits 0.0033, 0.0045, 0.0034, 0.0053 0.0048 MC-LR, CYL, OA, respectively. Selectivity studies were performed show absence cross-reactivity between analytes. Finally, application tap water samples revealed very good agreement calibration curves obtained in buffer. This could open window pollutants different matrices.

Abstract Along with an ever‐deepening understanding of the catalytic principle natural enzymes, rational design high‐activity biomimetic nanozymes has become a hot topic in current research. Inspired by active centers enzymes consisting sites and binding pockets, Cu‐doped CoS 2 hollow nanocube (Cu/CoS HNCs) nanozyme integrating substitution defects vacancies is developed through defect engineering strategy. It shown that Cu/CoS HNC serve as pockets sites, respectively. The construction this key center accelerated electron transfer from Co/Cu redox cycle significantly improve substrate affinity efficiency HNCs nanozymes, which results excellent performance nanozymes. Using superior enzymatic activity HNCs, fluorescence detection platform for alkaline phosphatase (ALP) established, wider range lower limit (LOD) than previous work. This work broadens family provide new idea development novel high enzyme activity, well guideline highly sensitive fluorescent sensors.
