Abstract
Tb-2(MoO4)(3) nanostructures are demonstrated for the first time to have an intrinsic peroxidase-like activity. Tb-2(MoO4)(3) nanoplates could efficiently catalyse the oxidation of 3,3',5,5'-tetramethylbenzidine (TMB) to generate a blue dye (with an absorbance maximum at 652 nm) in the presence of H2O2. Based on the highly efficient catalytic of Tb-2(MoO4)(3) nanoplates, a novel system for optical determination of H2O2 and glucose was successfully established under optimized conditions. The assay had 0.0.08 mu M and 0.1 mu M detection limit for H2O2 and glucose, respectively. In our opinion, this enzyme mimetic has a potential to use in other oxidase based assays.
