Abstract
Synthesis of nanoparticles using green synthetic route achieving much more importance, because of its simple, clean, nontoxic and eco-friendly approach and it is a better alternate for chemical and physical methods. This work demonstrates the bio-synthetic route for the synthesis of zinc oxide nanoparticles using Paspalidium flavidum (weed grass) plant extract. The synthesized nanoparticles were characterized using various analytical techniques. The photocatalytic degradation of amido black 10B dye was also performed using prepared nanoparticles under sunlight luminance. The antibacterial activity against Bacillus subtilis and Pseudomonas aeruginosa bacteria confirmed that biosynthesized nanoparticles exhibit excellent activity against B. subtilis.
