Abstract :
Gold nanoparticles has many applications in medical field such as drug delivery, bio-imaging, cancer therapy etc. Green fabrication of gold nanoparticles was studied using Desmostachya bipinnata (Halfa grass or Darbha). The aqueous extract of this used as reducing agent, mixed with the Chloroauric acid solution and the mixture was kept under continuous stirring. The color change of the solution into ruby red indicates the formation of gold nanoparticles was observed. The synthesized gold nanoparticles was characterized using UV- Visible spectrophotometer, the SPR band formed at 560.0 nm. Further, the synthesised gold nanoparticles were subjected to antioxidant property and anti-bacterial activity.
