A Review on Synthesis and Biological Evaluation of Plants Based Metallic Nanoparticles

Nanotechnology is a field of research and innovation concerned with building ’things’-generally, materials and devices on the scale of atoms and molecules. Nanotechnology has become very popular in the past few years. The development of synthesis of metallic nanoparticles has become a major focus of researchers. Metallic nanoparticles have become increasingly used because of their advantages including high stability and loding capacity. Nanoparticles can be synthesized chemically or biologically approaches. One of the most considered methods is the production of metal nanoparticles using organisms. Among these organisms, the plants seem to be the best candidates and are suitable for the large-scale synthesis of nanoparticles. Metallic nanoparticles that have immense application are industries of different type namely gold, silver, and copper, iron oxide and titanium magnetic, etc. the size of the nanoparticles are in the range of 1 to 100 nm. Characterization of synthesized nanoparticles is accomplished through UV spectroscopy, X-ray, FTIR, SEM, TEM, XRD, DLS and EDX. This review based on the recent scientific publications to synthesize metallic nanoparticles along with various methods for silver, copper and titanium metallic nanoparticles by using plants also the review explore the recent development in antibacterial, anticancer and biosensing application of metallic nanoparticles reported by the researchers during the last decades.
