 Electrochemical sensors are widely used in various fields including pharmaceuticals, drug detection, cancer detection, and analysis of toxic elements in tap water. They are characterized by their low cost, ease of manufacture, rapid analysis, small size, and ability to detect multiple elements simultaneously. Graphene, fullerene, carbon nanotubes, carbon graphite, glassy carbon, carbon clay, graphene oxide, reduced graphene oxide, and metals are all materials used in the construction of electrochemical sensors. Recent advances in electrochemical sensing technology have focused on improving the sensitivity and analysis speed of these devices through modifications with conductive materials like molecularly imprinted polymers, multi-walled carbon nanotubes, fullerene, C60, ironf3, nanoparticles, Fe3O4Np, and CuO microfragments, CuOMF.
