Bioreduction of chloroauric acid (HAuCl4) for the synthesis of gold nanoparticles (GNPs): A special empathies of pharmacological activity

Gold nanoparticles (GNPs) were prepared using plant extract a simple biological approach. The Hygrophila spinosa aqueous leaf extract has been carried out in the present study. The bioreduction of chloroauric acid (HAuCl 4 ) for the synthesis of gold nanoparticles with the plant extract H.spinosa . The plant extract is mixed with HAuCl 4 , The reduction of auric chloride led to the formation of AuNPs within 10 min at room temperature (28C), The size, shape and elemental analysis were carried out using X-ray diffraction, SEM-EDAX, DLS, FT-IR and UV-spectroscopy. The results showed that the leaf extract of H.spinosa is very good bioreductant for the synthesis of gold nanoparticles. The synthesized gold nanoparticles have more active against for human pathogens and also have good anticancer property.
