Tetramethyl Benzidine

Erythrocyte-like Cu1.8S nanoparticles exhibited excellent peroxidase mimetic properties and were able to catalyse tetramethyl benzidine (TMB) to its blue oxidized product in the presence of H2O2 following the Fenton reaction. The catalytic process was inhibited by glutathione (GSH) and this phenomenon was used to construct an efficient sensing platform for the colorimetric determination of glutathione.
