Abstract
Nanotechnology is making an impact in every field of life. Researchers are expending their interests towards synthesise of gold nanoparticles as they provide superior properties for different types of applications. Conventionally nanoparticles have been synthesised by various physical and chemical methods, having negative impact on environment. The production of nanoparticles using plant extract is alternative the conventional methods. The photosynthesis is a green and eco-friendly technology used for production of large scale nanoparticles. Plant extracts may act both as reducing agents and stabilizing agents in the synthesis of nanoparticles. The various phytochemicals present in plant extract used for the reducing and stabilisation of nanoparticles. This review article is concentrated on synthesis of gold nanoparticles using plant extract used for various applications.
