Green Synthesis of Gold Nanoparticles Using Piper Nigrum (Black Pepper) Aqueous Extract
Abstract: In the present study, we wish to report the green synthesis of gold nanoparticles using aqueous extract from fruit of black pepper. The extract with different concentrations was reduced with HAuCl4 aqueous solution at room temperature. The color change, pH change and UV-visible spectroscopic analysis reveal the surface plasmon resonance (SPR) of the final reaction product which confirms the reduction of Au3+ ion to gold nanoparticles. The FTIR spectra confirms …
