ABSTRACT
Metallic and metal oxide nanoparticles shows unique properties compared with inorganic and organic compounds developed from the same metals or metal oxides. Apart from silver, gold, and platinum, which have been treated as front-line metallic nanoparticles, other inorganic nanoparticles such as iron and iron oxide, copper and copper oxide, palladium, zinc and zinc oxide, magnesium, calcium, iridium, titanium dioxide, tin oxide, selenium, zirconium, nickel, silicone, lithium, etc., have also been gaining the attention of researchers. In this chapter we describe the various methods of fabrication and functionalization of these nanoparticles with special attention to the chemical aspects of functionalization. This chapter also emphasizes the biomedical and various other applications of metallic nanoparticles and deals with the key findings on the fabrication of nanocomposites and their significance. This chapter focuses on all of the versatile fabrication methods of functionalized nanoparticles, including the green approach employed to synthesize inorganic nanoparticles. Also considered in this chapter are the challenges encountered during fabrication and functionalization, including stability viewpoints.
