Green synthesis of copper oxide nanoparticles using the outer layer of Allium cepa L. and evaluation of its antimicrobial properties

The recent antimicrobial resistant to the present antibacterial agents has been biggest problem in treatment of infection. Over years, various strategies implemented overcome resistance available antibiotic agents. In regards this, phytochemical found plants like Allium cepa, which exhibited potent activity used by researchers as natural products fight against bacterial resistance. cepa also known commonly onion, is an herbaceous biennial plant amaryllis family (Amaryllidaceae) grown for its edible bulb. Copper oxide nanoparticles are one most vital nanomaterials biomedical application. phytochemicals extract were reducing and capping agent. aim study determine synthesized copper using (onion) aqueous extracts. dried outer layer was collected boiled. 150 ml mixed with 250 nitrate solution, purpose green synthesis. After reaction completed, centrifuged, decanted dried. characterized accessed activity. results UV-Vis Spectroscopy, FTIR, DLS particles size analysis, TEM XRD, obtained evaluated.
