Nanotechnology is now creating a growing sense of excitement in the field of life science. Nano particles can be synthesized by physical and chemical method but green synthesis method is the most emerging approach of preparation due to eco friendly and less time consuming procedure. This study aimed at green synthesis, characterization and evaluation of antibacterial effect of nano silver on mastitis causing bacteria. Aqueous coriander leaf extract with certain concentration of reducing agent were used for the production of silver nano particles. Characterization of synthesized silver nano particles was done by Zeta sizer analysis. The result of zeta sizer analysis reveals that the diameters of nano particles are within the range of nano scale. Transmission electron microscopy (TEM) analysis of silver nano particles was done to confirm the shape, size and morphology. Antibacterial activity of nano silver was investigated on mastitis causing bacteria such as E. coli, P. aeruginosa, S. aureus by well diffusion method. The antibiosis test result indicated that silver nano particles are able to inhibit E. coli and S. aureus but unable to inhibit P. aeruginosa. Therefore green synthesized nano silver can be used as anti microbial agent for mastitis causing bacteria.
