Biosynthesis and In-Vitro Study of Gold Nanoparticles Using Mentha and Pelargonium Extracts

Abstract

By green synthesis method utilization and using two plants, Mentha and Pelargonium plant extracts, gold nanoparticles were synthesized. For medical applications gold nanoparticles performance was observed in PBS media which is as like as human blood. Important features of green synthesized gold nanoparticles were measured using, GC-MS, UV-vis, FESEM, DLS and FT-IR. Main goal of this research was investigating reducing and stabilizing effects of mentioned plants, which was confirmed by GC-MS results. DLS and FESEM results proved nanometric size of green synthesized gold nanoparticles. For describing the performance, might be said that both extracts lead to synthesis of gold nanoparticles which their sizes are identical. Also, the synthesized gold nanoparticles from both plant extracts didn't agglomerated. Result of investigating performance of synthesized gold nanoparticles in PBS media indicates that both extracts will synthesize nanoparticles which will be stable by passing time or increased temperature.
