Scan rate Dependent Factor for Antioxidant Activity of Gold Nanofilms Synthesized via Cyclic Voltammetry Technique

Abstract

Gold nanoparticles (AuNPs) were found to act as antioxidants owing to their inert, high stability, biocompatibility, and non-cytotoxic. The present investigation involved the synthesis of gold nanoparticles through the electrodeposition technique on a substrate comprising Fluorine-doped Tin Oxide (FTO). By manipulating the scan rate parameter, an effective approach can be employed to facilitate precise management of particle morphology and size. The obtained shape of AuNPs were spherical and irregular. In this study, it was observed that gold nanoparticles elicited potent inhibition, particularly at a scan rate of 150 mV/s, with a markedly high inhibition value of 41.27%. The outcome was further supported by an augmented particle distribution density per unit area, which measured as 149,635,036.5/mm².

The Effect of Electrodeposition Voltage on the Antioxidant Activity of Gold Nanoparticles

“…Published by The Center for Science Innovation One of the most attractive alternative methods is the electrodeposition method. This method has been proven by many researchers to be capable of synthesizing AuNPs, resulting in the deposition of AuNPs onto the substrate surface to form a thin film [17][18][19][20][21]. The method provides several advantages, including simplicity, speed, and costeffectiveness.…”
