ABSTRACT

Nanoparticles of metals with size ranging from 1 to 100 nm have unique properties that assist in molecular diagnostics and therapies. Various methods including physical and chemical routes are available for synthesis of metal nanoparticles. Nanoparticles of metals such as silver and gold were synthesized in the aqueous medium using the 6 MeV electron irradiation technique. Metal nanoparticle solutions were characterized by ultraviolet (UV)-vis absorption spectroscopy, X-ray diffraction, transmission electron microscopy, and energy dispersive spectroscopy techniques. The synthesized metal nanoparticles were characterized using different techniques such as X-ray diffraction, UV-Vis absorption spectroscopy, transmission electron microscopy and energy dispersive spectroscopy. To understand nucleation and growth of metal nanoparticles in solution, it is necessary to know interaction of high-energy electrons with the medium. The higher stability and uniform distribution of metal nanoparticles in a gel matrix, without aggregation of small particles are some of the major advantages offered by such stabilizing polymers.
