BIO-SYNTHESIZED NANO-FORMULATION OF ZINC OXIDE – ALOE VERA AND TO STUDY THEIR CHARACTERIZATION AND ANTIBACTERIAL ACTIVITIES AGAINST MULTIPLE PATHOGENS

Nano-sized ZnO particles of specific morphology were synthesized using the plant leaf extracts of Aloe vera. In modern science Nanotechnology is an ablaze field for the researchers. Nanoparticles having a size of 1-100 nm in one dimension are used significantly concerning medical chemistry, atomic physics and all other known fields. Nanoparticles are used immensely due to its small size, orientation, physical properties, which are reportedly shown to change the performance of any other material which is in contact with these tiny particles. The biological approach is the most emerging approach of preparation, because, this method is easier than the other methods, eco-friendly and less time consuming. The semiconductor ZnO has gained substantial interest in the research community in part because of its large exciton binding energy 60 meV which could lead to lasing action based on exciton recombination even above room temperature. The Green synthesis was done by using the methanol of Aloe vera extract and zinc oxide. A fixed ratio of plant extract to metal ion was prepared and the color change was observed which proved the formation of nanoparticles. The nanoparticles were characterized by UV-vis Spectrophotometer, FTIR Analysis, XRD, and SEM.
