A colorimetric assay for H(2)O(2) and glucose based on the morphology transformation of Au/Ag nanocages to nanoboxes.
Aliakbarpour S, Amjadi M, Hallaj T. Aliakbarpour S, et al. Food Chem. 2024 Jan 30;432:137273. doi: 10.1016/j.foodchem.2023.137273. Epub 2023 Aug 25. Food Chem. 2024. PMID: 37660579
Herein, we introduced a sensitive colorimetric platform for hydrogen peroxide (H(2)O(2)) assay based on gold/silver (Au/Ag) nanocages with porous structure. In the presence of H(2)O(2), the morphology of hollow Au/Ag nanocages was converted to closed nanoboxes, alte …
