Efficient one-pot biosynthesis of silver nanoparticles using Entada spiralis stem powder extraction

Biosynthesis of noble metal nanoparticles is a vast developing area of research. In the present study, silver nanoparticles (Ag-NPs) are synthesized from aqueous silver nitrate through a simple and biosynthetic route using aqueous extract of Entada spiralis stem powder, which acted simultaneously as...
