Colorimetric-catalytic-fluorescence triple-mode lateral flow immunoassay based on Au@PtPd NPs for sensitive detection of capsaicinoids: Evaluation of edible oil and chili quality.
Rapid quantification of capsaicinoids (CAPs) is critical for identifying recycled cooking oil and the grading of chili pepper pungency. In this study, a CAPs-specific monoclonal antibody and trimetallic core-shell Au@PtPd nanoparticles (Au@PtPd NPs) were prepared, the bare Au@PtPd NPs exhibited excellent antibody-bindi...

MCOF-assisted and MnO2 nanozyme-triggered cascade dual-mode aptasensor for intelligent detection of Salmonella Typhimurium.
Conventional methods for detecting Salmonella Typhimurium in food often require lengthy procedures or specialized instrumentation. We developed a dual-mode aptasensor based on magnetic covalent organic frameworks (MCOFs) and MnO2 nanozymes. MCOF-AuNPs@apt captures bacteria, followed by MnO2@apt binding to form sandwich...

A cascade catalysis-enhanced microfluidic platform for rapid foodborne pathogen detection using Pt@Zr-MOF nanozymes.
Salmonella typhimurium (S. typhimurium) has become a major pathogen in the field of food safety, seriously threatening human health. Although mainstream diagnostic assays, including culture-based methods, enzyme-linked immunosorbent assay (ELISA), and molecular diagnostic technology, are generally reliable, each method...

Colorimetric-SERS Dual-Mode Detection of Organophosphorus Pesticides Using Au-R-Fe3O4 Nanozyme Cascade Platform: A Practical Approach for Chemistry Education
Organophosphorus pesticides (OPs) pose significant environmental and health risks due to their persistence and neurotoxicity, yet current detection methods rely on sophisticated instrumentation inaccessible to educational settings. To address this pedagogical gap, we developed a recyclable Au-R-Fe3O4 nanozyme cascade...
