The detection of endogenous phenolic compounds (EPs) in food is great significance elucidating their bioactivity and health effects. Here, a novel bifunctional vanillic acid-Cu (VA-Cu) nanozyme with peroxidase-like laccase-like activities was successfully prepared. peroxidase mimic behavior VA-Cu can catalyze 3,3',5,5'-tetramethylbenzidine (TMB) to generate oxidized TMB (oxTMB). Owing the high reducing power EPs, this process be inhibited, degree inhibition increases increase reaction time. Additionally, owing outstanding laccase VA-Cu, it facilitate oxidation various resulting formation colored quinone imines, catalysis Based on interesting experimental phenomena mentioned above, six-channel sensor array (2 enzyme-mimic × 3 time points = 6 sensing channels) constructed, achieving discriminant analysis nine EPs. In addition, combination artificial neural network (ANN) algorithms arrays has achieved accurate identification prediction EPs black tea, honey, grape juice. Finally, portable method for identifying been proposed by combining smartphone.

Enrofloxacin (ENR) is a commonly used veterinary antibiotic and poses health risk when present as residues in food. This study describes dual-mode immunochromatographic test strip (DITS) biosensor for the detection of ENR Magnetic graphene oxide nanoparticles (MGO-NPs) are two-dimensional magnetic nanomaterials with large specific surface area fine biocompatibility, which can better provide more adsorption points biological antibodies. Gold (AuNPs) stimulate localized plasmon resonance effect under laser irradiation, will increase temperature to achieve photothermal conversion. The conversion efficiency MGO-NPs be effectively enhanced by combining AuNPs form MGO@Au nanocomposites (MGO@Au-NCs). Then, MGO@Au-NCs were combined an monoclonal antibody MGO@Au@Ab probe, MGO@Au@Ab-DITS was developed. employed assess samples spanning concentrations from 0 1000 μg/mL. Sample solutions containing mixed solution, deposited on strip's sample pad, analyzed using both colorimetric methods employing 808 nm infrared imaging instrument. results show that sensitivity mode sensor 0.0159°C whereas, standard deviation (SD) limit (LOD) 0.058 10.89 μg/mL, respectively quantification (LOQ) 36.31 In mode, developed 5.222 au, SD, LOD LOQ 40.13, 23.05 and76.85 respectively. innovative system has been applied detect food such juice milk, laying groundwork other drug
