302MoS2-MIL-101(Fe)detecting glucoseglucoseColor0.01-15μM0.01μM
302MoS2-MIL-101(Fe)On the basis, a sensitive method for H2O2 detection was proposed with a linear range of 0.01−20 μmol/L and a detection limit of 10 nmol/L. Considering H2O2 as product in the reaction of glucose catalyzed by glucose oxidase, a sensitive and selective method for glucose detection was proposed. The method can be used in blood glucose detection with good accuracy.H2O2Color0.01−20μM10nM
