Plant Extracts Derived Silver Nanoparticles

The plant aqueous solution and silver nitrate solutions were developed individually. A quantity of 1.5 ml of plant extract was mixed with 30 ml of 10-3 M of silver nitrate for the synthesis of silver nano particles. During silver nanoparticles synthesis, the change of color from pale greenish to brownish color suggested the
