BIOLOGICALLY DERIVED COPPER NANOPARTICLES AND ANTIMICROBIAL PERFORMANCE ANALYSIS

Abstract

This study focuses on the green synthesis of copper nanoparticles (CuNPs) using Garcinia pedunculata leaf extract. Plant-based synthesis is an eco-friendly and cost-effective method compared to conventional chemical techniques. The formation of nanoparticles was confirmed using UV–Visible spectroscopy and Scanning Electron Microscopy (SEM). The results showed a characteristic absorption peak, indicating successful synthesis of CuNPs with nanoscale structure. The synthesized nanoparticles were further tested for antimicrobial activity against selected bacteria and showed significant antibacterial effects. These findings suggest that biosynthesized CuNPs can be used as an effective and sustainable material for environmental and biomedical applications.
