- •
Graphene was produced by electrochemical reduction, which is green and efficient.
- •
A biosensor based on electrochemically-reduced GO, CS and Hb was constructed.
- •
The biosensor had a wide linear range of and a low detection limit for CH3NO2 detection.
- •
The biosensor has been applied in real samples, with high selectivity and stability.
