Popis: Graphene oxide phenoxyamide nanofilm (AP-GO) was covalently grafted on to polycrystalline gold platform by using cyclic voltammetry (CV). Initially, nitrophenyl (NP-) group was attached to the polycrystalline gold (Au) substrate through the electroreduction of 4-nitrobenzene diazonium salt (NB-DAS). Thereafter, nitrophenyl-modified electrode (Au-NP) was exposed to negative potential scan to reduce the nitro group to amine group (AP-). 4-Aminophenyl modified gold platform (Au-AP) was dipped into a electrochemically synthesized graphene oxide solution containing 1-ethyl-3(3-(dimethlyamino) propyl)-carbodiimide (EDC) as an activating solution. Thus formed Graphene oxide phenoxyamide modified gold substrate was denoted as Au-AP-GO. The nanoplatform was characterized by electrochemical method like cyclic voltammetry (CV) and spectroscopic techniques such as X-ray photoelectron spectroscopy (XPS) and diamond crystal accesorized attenuated total reflectance infrared spectroscopy Delivered by (ATR-FTIR). Publishing Layer Technology thickness to: of Elsevier the nanofilms BV on gold substrate was measured using an ellipsometer. Copyright © 2015 American Scientific Publishers All rights reserved.
