ABSTRACT

Objectives:The green biosynthesis of nanoparticles play a vital role in present day research because of their wider application in many fields of biological science and medicine. The biosynthesis of silver nanoparticles are done using dried leaves of Boerhaavia diffusa (S1) and Cichorium intybus (S2) by reacting these samples with 1mM concentration of silver nitrate. Methods: Characterization are done using UV Spectroscopy, XRD, SEM, EDAX and FTIR, Antibacterial and antifungal studies are carried out for synthesized nanoparticles using two plant sources. Results: UV , XRD, SEM, EDAX and FTIR confirms the formation, crystal structure, size, elemental silver formation and functional group responsible for the capping and stabilization of nanoparticles. Both plants sources are possessed antibacterial and antifungal activities. Conclusion: Boerhaavia diffusa L. and Cichorium intybus L. plant sources have good capabilities for synthesize silver nano particles by biological route. Synthesized nanoparticles by both sources have antibacterial and antifungal properties.
