The green synthesis of gold nanoparticle using extract of Virola oleifera

Abstract

The green synthesis consists of an environmentally friendly method of producing gold nanoparticles (AuNP's). Physical and chemical syntheses have energy intensive and may involve toxic chemicals, while biological techniques are cost-effective, clean, non-toxic and environmentally appropriate. Virola oleifera is widely used in folk medicine. The bark of the trunk when scraped produce a resin rich in phenolic compounds, which is used against bleeding hemorrhoids, cramping, and also has healing action of chronic wounds and ulcers, diarrhea and counter hemoptysis. It is known that the presence of phenolic extract gives the reducing action, but studies need to be done to understand what substances are involved and what the mechanisms of formation of newly synthesized nanoparticles. Thus, the aim of this study was to describe a new route for the synthesis of AuNP's using resin of Virola oleifera with future application in nanoscience from the synthesis of nanoparticles for applications as nano biosensors.
