文摘
- •
Carbon-based AuAg bimetallic nanocomposite was synthesized using carbon dots.
- •
The as synthesized Au-Ag/C NC exhibits good optic response toward H2O2.
- •
The SPR absorbance of Au-Ag declined and red-shifted with the color change.
- •
A simple colorimetric and UV strategy for sensitive detection of H2O2 is proposed.
- •
This colorimetric strategy can also be applied in detection of lactate by naked eye.
