One-Pot Scalable Synthesis of rGO/AuNPs Nanocomposite and Its Application in Enzymatic Glucose Biosensor

A nanocomposite, rGO/AuNPs, was synthesized simultaneously using one-pot approach with gold nanoparticles (AuNPs) and reduced graphene oxide (rGO) within gelatin which used as a reducing and stabilizing agent. Then, the fabricated nanocomposites were characterized by UV-Vis, transmission electron mi...
