Abstract
The bio-synthesis of gold nanoparticles is achieved by the reduction of gold metal ions in interaction with the aqueous plant extract of Kalanchoe pinnata. An absorption peak of the biosynthesized gold nanoparticles is detected at the wavelength range of 350 – 700nm. The UV-Visible spectra of gold nanoparticles synthesized by Kalanchoe pinnata extract shows maximum absorption peak at 530nm. The morphological features of gold nanoparticles were analysed by Scanning Electron Microscope that confirms the spherical shape of gold nanoparticles. The elemental analyses of gold nanoparticles synthesized by Kalanchoe pinnata extract extract have the weight percentage of gold as 50%. The study reveals that the synthesized gold nanoparticles shows potential antioxidant activity.
