Brassica juncea had better metal accumulating ability and later assimilating it as nanoparticles, Brassica juncea when hydroponically grown in solution of AgNO 3,Na3 Ag(S 2 O 3)2, and Ag(NH 3)2 NO 3 synthesized AgNPs of nm . e concentrations of plant extracts which are aqueous or
Nov 25, 2021 3. Biosynthesis of silver (Ag) nanoparticles. Plants have the ability to store heavy metals in their various parts. As a result, biosynthesis techniques employing plant extracts have produced a simple means to stabilize efficient growth, simple, cost-effective synthesis process, along with traditional preparation methods for the production of NPs .
The primary requirement of green synthesis of AgNPs is silver metal ion solution and reducing biological a agent. In most of the cases reducing agents or other constituents present in the cells acts as stabilizing and cap-ping agents, so there is no need of adding capping and stabilizing agents from outside. 2.1.
