GREEN SYNTHESIS OF ZINC OXIDE NANOPARTICLES USING GRAPE SEED EXTRACT AND ITS CHARACTERIZATION

Background: Nanotechnology (NPs) is a new technology in science with huge applications including medicine and pharmacology industries. In this study, cost effective and an eco friendly green synthesis has been employed to the fabrication of zinc oxide nanoparticles from the non-toxic grape seed extract as a reducing agent.

Aim: To synthesize and characterize grape seed extract mediated zinc oxide nanoparticles.

Materials and Methods: The synthesis of the zinc oxide nanoparticles was done with green synthesis. Morphological characters like the shape and size of the obtained green synthesised zinc nanoparticles done by transmission electron microscopy (TEM).

Results: The results confirmed that the synthesised grape seed extract mediated nanoparticles are eco-friendly, good and non toxic. The visual colour change observed in the graph seed extract solution shows the presence of zinc oxide nanoparticles. The particle size ranges from 20 to 30 microns, which clearly demonstrated the presence of spherical shaped ZnO NPs. The absorption formed in the reaction media has an absorbance peak at 410 nm. The TEM shows spherical shape and versatile nanoparticles. They appear to be arranged in a cluster and open superstructures.

Conclusion: In this study, a simple, biological and low-cost approach was done for the preparation of zinc oxide nanoparticles using grape seed extract. Thus the synthesised grape seed extract mediated zinc oxide nanoparticles can be subjected to the various other biological activities such as antibacterial, antifungal, cytotoxic evaluation to know the efficiency of these nanoparticles.
