Ultrafine and monodispersed iridium nanoparticles supported on nitrogen-functionalized carbon materials (Ir/NC) were prepared and served as an efficient oxidase mimic for 3',5,5'-tetramethylbenzidine (TMB) oxidation. Due to the inhibition effect of glutathione (GSH) on TMB oxidation, a sensitive colorimetric GSH detection approach was proposed.
