Name: NIR fluorescence Ag NCs
Composition: CuO, PMMA, and Ag
Particle size: 5 nm
Application: detection
Storage conditions: -4℃
Other instructions: sealed state shelf life of half a year [main advantages] 1, CuO NPs has inherent glutathione peroxidase (GPx-like) and peroxidase (POD-like) activity, Can catalyze GSH and O2 to generate hydrogen peroxide (H2O2), Further generate the OH; 2, the fluorescence intensity of Ag NCs decreased with the addition of GSH, This is because the sulfhydryl group (-SH) is easier to fix on the Ag NCs surface in GSH, Leaving the stabilizer PMAA away from the Ag NCs surface, When GSH occupies the silver site Ag NCs, -NH2 reacts with-COOH of PMAA in GSH, The combined effect of GSH and PMAA caused Ag NCs aggregation to form larger and non-fluorescent Ag NPs.
