Plant-extract mediated synthesis of ZnO nanoparticles using Pongamia pinnata and their activity against pathogenic bacteria

Bio-mediated synthesis of metal oxide nanoparticles using plant extract is a promising alternative of traditional chemical synthesis. The present study reports the synthesis of ZnO nanoparticles by biological method. Highly stable and hexagonal phase ZnO nanoparticles were synthesized using Pongamia pinnata leaves extract and were characterized by XRD, UV–vis, DLS, SEM, TEM and FT-IR spectroscopy. The synthesized ZnO nanoparticles were confirmed...
