An easy and facile method of biosynthesizing silver nanoparticles (AgNP) is presented. With an attempt to utilize aquatic fernAzollapinnata, its aquatic extract was used to reduce silver nitrate (AgNO3) to silver nanoparticles. The synthesis occurred at room temperature just after mixing the extract with the salt solution which was detected by UV-Vis spectrophotometer that gave its characteristic absorbance at 445 nm. FTIR image reveals the functional groups which are responsible for reducing and capping the silver nanoparticles. SEM and TEM images show the spherical shape and size of the formed particles. Fluorescent microscopic study also shows the spherical silver nanoparticles. These results proves Azollapinnata to be a good source of reducing agent for the environment friendly and low cost synthesis of silver nanoparticles.
