Enhanced reversible redox activity of hemin on cellulose microfiber integrated reduced graphene oxide for H 2 O 2 biosensor applications.
Carbohydrate Polymers(2019)
摘要
•A novel H2O2 biosensor based on hemin/RGO-CMF composite.•Vitamin C assisted synthesis of RGO-CMF composite.•The RGO-CMF improve the hemin redox electrochemistry by 6 folds compared to RGO.•High sensitivity, lower LOD with a wider linear response range of H2O2 has been achieved.•The sensor can be directly used for the sensitive detection of H2O2 in food and environmental samples.
