Abstract Gold nanoparticles (AuNPs) have attracted much attention as one of the most effective agents with high catalytic activities for radical scavenging reactions. Many studies investigated its antioxidant activity using various in vitro methods and shown promising action. In this research, we demonstrated synthesis Au nanofilms (AuNFs) by cyclic voltammetry technique evaluated their activity. The application a range voltage levels was utilized AuNFs, potential subsequently assessed through 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay. All AuNFs exhibited which increased upper reduced from 1,5 V to 0,75 V. increase gradually longer incubation times before DPPH assay, indicating significant impact on performance. obtained inhibition percentage ranging 8,26% 22,91%. highest could be achieved synthesizing 0,75V incubating it 90 minutes prior variations applied influenced morphological characteristics leading surface area, while duration found enhance efficacy reaction between DPPH. conclusion, successfully synthesize
