Abstract :

Nano sized materials have been an important subject in basic and applied sciences. A novel, low-cost, green methodology based mango juice extract mediated biosynthesis of silver nano particles (AgNPs) was reported. The resulting nano particles were characterized by UV-Visible spectrum, FTIR, TEM and SEM with EDX. FTIR showed characteristic bands (1650 and 3430 cm-1) finds the role of carboxyl group OH stretching amine NAH stretch in the formation of AgNPs. The morphological characterization was analyzed by SEM and the analysis showed the NPs smooth shaped, spherical and uneven. The antibacterial activity of the synthesized AgNPs was assessed by agar diffusion method and XTT assay against Escherichia coli and Staphylococcus aureus. Further the effect of nano particles on the surface morphology of bacteria was also shown employing SEM and TEM techniques.
