Question

Chemical synthesis of silver nanoparticles

Answer 1

Synthesis and characterization ofsilver nanoparticles by chemicalreduction method. Abstract:Nanoparticles, compared to microc particles have distinctly different properties and advanced characteristics. ... Silver nitrate is taken as the metal precursor and sodium borohydride as a reducing agent.Biological synthesis of silver nanoparticles

The white rot fungi Pycnoporus sp (HE792771) was grown in malt extract broth containing glucose10 g/l, malt extract 5 g/l. The final pH was adjusted to 6.0 and the flasks were incubated in the orbital shaker at 200 rpm at 32 °C. After five days of incubation, the mycelium was separated by filtration and supernatant was challenged with equal amount of silver nitrate solution of 1 mM (prepared in deionised water) and incubated in shaker at 200 rpm in dark condition at 32 °C . Simultaneously, a positive control of silver nitrate solution and deionised water, and a negative control containing only silver nitrate solution were maintained under same conditions.
