2-D hybrid material was fabricated by electrodeposited reduced GO-MB onto GCE.
The ERGO-MB/GCE was used as H2O2 biosensor for the electrochemical detection of H2O2 under physiological conditions.
The H2O2 biosensor exhibits performance including high sensitivity and selectivity, broad linear range and quick response.
The developed sensor could be well distinguished cancer cells from normal cells through H2O2 sensing.
