Abstract:
The phyto-mediated biosynthesis of nano-metals offers many advantages over classical methods, being a low-cost, nontoxic, eco-friendly approach which uses the “green” chemistry principles. The plants are found in abundance in nature and represent attractive raw materials to get metallic nanoparticles (MNPs), because they are inexpensive, safe and environment-friendly. Moreover, plant extracts contain many bioactive molecules that act as both reducing and stabilizing agents in MNPs synthesis, giving interesting properties to nanometals. The phytosynthesis of metallic nanoparticles is monitored by UV-Vis absorption spectroscopy. Different other biophysical methods are used for MNP characterization.
