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...
