Abstract


According to WHO, world is heading towards post antibiotic era means small disease and infections which have been curable from decades can kill once again. Presently, AMR (Antimicrobial Resistance) is a global threat asbacteria’s are continuously evolving with new defensive mechanisms. In this direction Nano bioscience has gained increased attention for discovering the bactericidal effect of metal nanoparticles with various shapes and diameter.This is due to the novel properties of nanomaterials including small size, large specific surface to volume ratio, their close interaction and high reactivity with microbial membranes.In the present workpure and copper doped ZnO nanoparticles have been synthesized using green synthesis and mechanical assisted thermal decomposition process.The samples were characterized using TEM, UV-Vis, XRD and FTIR. The nanoparticles were tested for their antibacterial activity against Gram-positive and Gram-negative bacteria: Staphylococcus aureus, Streptococcus progenies and Escherichia coli using shake flask method.andphoto catalytic activity using methylene blue as model organic dye.The antibacterial activity of samples is attributed to four main mechanisms: oxidative stress, coordination effect, and non-homeostasis and contact killing
