5192 302 MoS2-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. H2O2 Color 0.01−20 μM 10 nM
