Phyto-assisted synthesis and characterization of silver nanoparticles from amaranthus dubius.

The aqueous extract of Amaranthus dubius was used for the green synthesis of silver nanoparticles from silver nitrate solution under various conditions. The silver nanoparticles were characterized by spectrophotometric, physical and theoretical methods. The size of silver nanoparticles ranged from 10-70nm. The present approach of biosynthesis of silver nanoparticles using aqueous extract of A.dubius appears to be cost efficient, eco-friendly and an easy alternative to conventional chemical method of synthesis.
