Bimetallic Au-Ag Nanoclusters as a Photo-Responsive Oxidase-Like Nanozyme for Antioxidant Detection and Intracellular Redox Analysis. [PDF]

open access: yesSmall Sci
Gold–silver nanoclusters act as light‐activated enzyme mimics that generate peroxyl radicals, oxidizing thiamine into a fluorescent product. Antioxidants block this conversion, providing the basis for rapid, reagent‐free detection and accurate measurement of total antioxidant capacity in fluids and products.
