Graphitic oxide
WebAn improved method for the preparation of graphene oxide (GO) is described. Currently, Hummers’ method (KMnO 4, NaNO 3, H 2 SO 4) is the most common method used for preparing graphene oxide. We have found that excluding the NaNO 3, increasing the amount of KMnO 4, and performing the reaction in a 9:1 mixture of H 2 SO 4 /H 3 PO 4 … WebFabrication of poly-arginine on graphene oxide (GO)-graphite substrates was carried out by electropolymerization. • Fabricated poly-Arg/GO-based sensor was used for detection of fenitrothion. • Poly-arginine/GO has synergetic effect on the reduction of fenitrothion. • A label-free, non-enzymatic, and sensitive biosensor was achieved. •
