  The immobilization of horseradish peroxidase (HRP) enzyme causes protections on catalytic activities in determination of H2O2. The rate of electron transfer from redox enzyme onto the electrode surface is an important topic in bioelectrochemistry that could improve more the function of HRP biosensor by means of increasing electrode conductivity. Referring to this basis, effect of various nanoparticles are evaluated and compared with each other on the operation promotion in this review and Glassy Carbon Electrode (GCE) is utilized as a main foundation on immobilization of nanoparticles and HRP enzyme. Electrodes have been compared by the rate of current transfer in the optimum voltage data in the presence of Carbon-coated Iron Nanoparticles (CIN), Quantum Dots (QDs), Au and Laponite/Chit nanoparticles. Consequently in the same scan rate, HRP/Au/GCE (28 μA) ha.. Read More»
