Metallic nanoparticles have attracted scientist for nearly a century and now they are applied into different high technological fields. The huge interest is due to their fascinating and unique properties such as, high surface area to volume ratio which increase their activity in chemical processes and allow for the modification with different chemically functional groups. Others such as magnetic and optical properties which are related to the nano-size of the particles increased the areas where these particles are being applied. Now a days, metallic nanoparticles are used in biotechnology, magnetic separation, targeted drug delivery, and vehicles for gene and drug delivery. They are also used in industry to produced enhanced materials and composites and in the production of high-tech electronic devices. There are various examples that can be shown for the used metallic nanoparticles, their oxides and compounds which show their importance in recent technology. Au (Gold) Nanoparticles...

Drug delivery is one of the most important subject of research in medical sciences. The increase of the drug efficacy and the reduction of the side effects are among the goals of the research in this field. Scientists are working on the development of metallic nanoparticles which target the infected cells without doing harm to other neighbor cells. Au (Gold) nanoparticles, Ag (Silver) nanoparticles, Fe (Iron) nanoparticles and Cu (Copper) nanoparticles are the most researched nanoparticles which show high potential in site-specific drug delivery. These nanoparticles have unique physical and chemical properties such as, plasmatic resonance, fluorescent enhancement, and catalytic activity enhancement which make them very fascinating materials in drug delivery applications.
