CHARACTERIZATION PROFILE OF PLANT MEDIATED BIOGENIC SILVER NANOPARTICLES: AN OVERVIEW

Nano-biotechnology is at leading edge of research development, making an impact in all spheres of human life. The size of nanoparticles is comparable to that of most of biological molecules (e.g., proteins, DNA) and structures (e.g., viruses and bacteria) therefore; nanoparticles can be developed for diagnostic devices, contrast agents, analytical tools, physical therapy applications, and drug delivery vehicles. This review illustrates possibilities of development of reliable experimental protocols for the bio synthesis of nanomaterial’s using different plant extracts by performing analytical comparisons of characterization techniques like Ultra Violet visible spectroscopy, Scanning Electron Microscope, Transmission Electron Microscope and X-Ray Diffraction. Biological methods of synthesis have paved way for the “greener synthesis” of nanoparticles and these have proven to be better methods due to slower kinetics, being environmentally friendly, less expensive. Also they offer better manipulation and control over stabilization of nanoparticles.
