Copper (II) Oxide and Graphene as Composite Materials for Glucose Biosensors

Copper (II) oxide - graphene composite materials were prepared on the electrode surface in the solution of CuCl2. The resulting composite material was characterized by cyclic voltammetry on surface of the glassy carbon electrode. Prepared copper (II) oxide - graphene nanocomposite was scraped from the electrode surface and Raman spectra was measured by optical tweezers combined with micro Raman spectroscopy. This composite nanomaterial was used on determination of glucose and can be used to construct bio batteries, too.
