Biosynthesis of silver nanoparticles is an eye catching area of a modern research field. It is simple, single step, non toxic and eco friendly method. In the present investigation, the aqueous extract of Bauhinia tomentosa is used to synthesise silver nanoparticles and it was confirmed by UV Visible spectrometer. Due to surface Plasmon resonance, the peak obtained at 440.0 nm. The functional group present at the surface of the silver nanoparticles was confirmed by FT IR analysis. Further, the synthesized silver nanoparticles were subjected to antibacterial activity by Well diffusion method and also antioxidant activity performed by hydrogen peroxide scavenging assay. As concentration of silver nanoparticles increases the bactericidal activity is raised and also the antioxidant activity is increased. Thus it reveals that due to presence of various bioactive compounds present in the plant extract acting as reducing agent to reduce the size of silver ions into silver nanoparticles. Therefore, the biosynthesized nanoparticles is utilized for various biomedical applications.
