We have modified a glassy carbon electrode (GCE) with copper(I) oxide nanoparticles (NPs), nitrogen-doped graphene (N-graphene) and Nafion to obtain a novel sensing platform for the non-enzymatic detection of hydrogen peroxide. The deposition of the Cu2O NPs on N-graphene was accomplished by single-step chemical reduction. The nanocomposite was characterized by using X-ray diffraction and scanning...
Acid-treated multi-walled carbon nanotubes (MWNTs) were immobilized on the surface of a glassy carbon electrode to form an MWNT-modified electrode. The electrocatalytic response of the modified electrode towards tryptophan (Trp) was investigated by cyclic voltammetry (CV) and differential pulse voltammetry (DPV). The results demonstrated that the modified electrode exhibited a high degree of catalytic...
