A variety of nanoparticles were formed when the concentration of the reducing agent was increased with respect to the silver nitrate solution. The reaction mixtures displayed variation in colours and characteristic UV-VIS spectra of silver nanoparticles with the increasing concentration of colocasia extract. A single SPR band in between 419 to 438 nm in UV-VIS spectroscopy revealed the formation of silver nanoparticles. TEM analysis of the silver nanoparticles confirmed the spherical shape and size distribution of the nanoparticles found in the range of 10-30nm. Antibacterial activity of the Ag-NPs was confirmed by disk diffusion method against Bacillus flexus, Escherichia coli, Serratia marcescens and Staphylococcus aureus.
