Antibacterial Activity of Copper Nanoparticles Synthesized by Bambusa arundinacea Leaves Extract

Abstract

A novel bio-fabrication of copper nanoparticles (CuNPs) using Bambusa arundinacea leaves aqueous extract solution, and their prospective biological activities are reported. Scanning and Transmission Electron Microscopy study of synthesized powder confirms the formation of Cu NPs with a size range 15-30 nm. The Dynamic Light Scattering (DLS) study further confirms the average particle size as 24.4 nm, and the observed zeta potential value of -16.1 mV affirms the high stability of Cu NPs. The synthesized Cu NPs exhibited potent antibacterial activity against Escherichia coli, Staphylococcus aureus, Bacillus subtilis, and Proteus vulgaris. This method provides a safe, clean, eco-friendly, and economical way to produce Cu NPs.
