ZnO Nanoparticles; synthesis, spectral characterization, and antibacterial activity - an ecofriendly approach

The synthesis of metal oxide nanoparticles with the use of plant extract is a promising alternative to the conventional chemical method. This is work aimed to synthesize Zinc Oxide nanoparticles using plant leaves extract of Aegle marmelos, and investigation of its antibacterial activity. Aegle marmelos leaves are of considerable interest and are a well-known compound because of its antioxidant, antibacterial, and antifungal activities, etc, In the present study focus is on the green synthesis of ZnO nanoparticles by potassium hydroxide, Zinc acetate, and bio components of leaves of Aegle marmelos. Further, the green synthesized ZnO nanoparticles were characterized by UV -Visible spectrophotometer (UV-Vis), X-ray diffraction analysis(XRD), Fourier transform infrared (FTIR), and Scanning electron microscope (SEM) techniques. This analysis confirms the formation of ZnO nanoparticles. The antibacterial activity of the ZnO nanoparticles was evaluated by testing against Gram-positive (S. aureus) bacteria. The antibacterial activity of the synthesized ZnO nanoparticles was found to be more effective against gram-positive bacteria (S. aureus).
