An effective and affordable technique for detecting a variety of substances biological, medical, environmental significance is electrochemical sensing (ECS). Due to their distinctive structures abilities offer robust electrocatalytic activity with little surface fouling, low cost, biocompatibility, simple electron transfer kinetics, carbon materials-based electrodes like graphene (GR) nanotube (CNT) are frequently used the development sensors. Since GR has large specific area, it can host number biomolecules still have decent detection sensitivity. Along important developments in synthesis, purification, conjugation, biofunctionalization GR, device integration technologies nanofabrication evolved. Combinations aforementioned characteristics accelerated GR-based sensors many critical bio-analyses. The rapid bioanalyses better sensitivity selectivity been facilitated by combination features. Direct transport between enzyme active electrode region made possible application GR. It easily construct execute on-site oxidases dehydrogenases improved thanks excellent electro-catalytic activities on redox reaction hydrogen peroxide (H2O2) nicotinamide adenine dinucleotides (NADH). GR's oxidation NADH, thiols, H2O2, other interfering species occurs at potentials, use effectively suppresses these species. two benefits clinical chemistry, food quality control, wastewater treatment, bioprocessing great resistance fouling selectivity.
