Antibacterial effect of silver nanoparticles synthesised on a polycarbonate membrane

This work reports for the first time the possibility of green synthesis and the antibacterial effect of silver nanoparticles (AgNPs) on commercialized polycarbonate membrane. The AgNPs were loaded on the polycarbonate membrane serving as the substrate via ultra-sonication and centrifugation. The extracts from the red flowers of Callistemon viminalis were used as the chelating agent. The synthesised thin film silver nanoparticles were characterized by various techniques such as Scanning Electron Microscope (SEM), Energy Dispersive X-ray spectroscopy (EDX), Fourier transform-infrared (FT-IR), X-Ray diffraction and UV-Vis spectroscopy. Consequently, the antibacterial affect was studied. The synthesised thin film silver nanoparticles had a surface plasmon resonance of 310 nm and show a very effective inhibition growth of both Gram-positive and Gram-negative. (C) 2019 Elsevier Ltd.
