The detection of small molecules is critical in many fields, but traditional electrochemical methods often exhibit limited accuracy. construction multi-mode sensors a common strategy to improve However, most existing rely on the separate analysis each mode signal, which can easily lead sensor failure when deviation between different results too large. In this study, we propose based Prussian Blue (PB) for ascorbic acid (AA) detection. We innovatively integrate back-propagation artificial neural networks (BP ANNs) comprehensively process three collected signal data sets, successfully solves problem caused by large results, and greatly improves prediction accuracy, range, anti-interference sensor. Our findings provide an effective solution optimizing multi-modal sensors, show broad application prospects bioanalysis, clinical diagnosis, related fields.

Developing sensitive and highly active nanozymes for antioxidant analysis is of the utmost significance in medical diagnosis health monitoring due to their essential roles as free reactive oxygen species scavengers. Here, six metal-organic frameworks (MOFs)-based are developed a dual-mode absorbance/image colorimetric sensor array simultaneous discrimination determination various antioxidants with comparable structural or chemical properties. The catalysts exhibit wide range potent oxidase-like catalytic activities, verified by kinetic parameters, presence dispersed transition metallic bimetallic redox nodes. These efficiently catalyze oxidation colorless 3,3',5,5'-tetramethylbenzidine (TMB) blue TMBox, resulting noticeable absorption RGB color changes at 650 nm. Various demonstrate different reducing capabilities leading generation fingerprint-like spectral patterns. pattern recognition chemometrics methods including principal component (PCA) linear discriminant (LDA) represent well-separated clustering ascorbic acid, dopamine, uric cysteine, glutathione, thiocyanate, tannic gallic acid. assay provides detection (0.1-75 μM) limits low 30 nM. successfully discriminated concentrations, mixtures, interferences. Furthermore, sensor's applicability biologically relevant was validated urine plasma samples. Overall, MOF-based nanozyme offers promising platform discriminating determining potential applications.

The development of sensitive and accurate glucose biosensors is significant in diabetic patient monitoring. Here, we synthesize carbon-decorated Fe3O4 nanotubes (Fe3O4@C NTs) using a rational designed template method. Through catalytic oxidation typical colorimetric reaction, the prepared Fe3O4@C NTs showed significantly better peroxidase-like oxidase-like performances than other similar Fe3O4-based nanomaterials. Moreover, optimal pH, temperature, concentration for were 4.0, 60 °C, 40 μg/mL, respectively. We additionally investigated steady-state kinetics NTs, their catalyzed reactions found to follow Michaelis–Menten model. Based on activity they employed label-free, rapid, selective, highly detection H2O2 glucose, demonstrating potential application determination.
