The bio molecules present in the plant induced the reduction of Au3+ ions from HAuCL 4, resulted in the formation of Gold nanoparticles. The growth of nanoparticles was monitored by Uv-Vis spectrophotometer that demonstrated a peak at 540nm. Particle size Analyser and Transmission electron microscopy (TEM) were used to find the size and shape of the Gold nanoparticles. Gold nanoparticles were 20-30nm in size and their shape varied from spherical to triangular and hexagonal poly shaped. X-ray Diffraction analysis (XRD) studies corroborated that the biosynthesized nanoparticles were crystalline gold. Energy dispersive spectroscopy (EDAX) confirmed the presence of an elemental gold signal. Fourier transform-infrared (FTIR) spectroscopy analysis revealed that biomolecules were involved in the synthesis and capping of gold nanoparticles.
