A sensitive hydrogen peroxide biosensor using ultra-small CuInS2 nanocrystals as peroxidase mimics

- Fluorescent CuInS2 nanocrystals are synthesized by microwave-assisted method.
- As a mimic peroxidase, CuInS2 nanocrystals exhibited good catalytic properties.
- A sensitive and selective approach for the detection of H2O2 was developed.
