Green Synthesis (Using Plant Extracts) of Ag and Au Nanoparticles

The integration of green chemistry to nanotechnology is one of the most alarming and explored area for the nanoscience researcher. The towering environmental issues had attracted the researchers towards the novel green synthesis of nanoparticles in biological systems such as bacteria, fungi and plants [3]. However, exploration of the plant extracts as the medium of synthesis has heightened interest due to its simplicity, easiness and viable approach and also, the use of plant extracts for the synthesis of nanoparticles does not require elaborate processes [3,4]. Plant extracts acts as a natural reducing and stabilizing agent at ambient condition (Figure 1). Various nanoparticles such as Ag, Au, Pt and Pd have been synthesized via various green synthesis by many researchers [4,5].
