Abstract
Nanomaterials play very prominent role in physical, chemical and biomedical engineering applications due their high surface energies. Also the electronic configuration of atoms within the materials is very important since this principally detrmines the type of bonding and thus electrical, optical, luminescent, mechanical and magnetic properties. At nanoscale dimensions, materials exhibit entirely different properties as compared to thieir bulk counterpart. Noble metallic nanoparticles/nanostructures exhibit interesting feature of localised surface plasmon resonant; absorption can be tuned from ultraviolet region to infrared region of electromagnetic spectrum and this field has been developed to deliver potential applications in photonics, optoelectronics, optical-data storage, solar cells, filters, sensors not to mention the considerable scope in medical engineering, such as DNA labeling, tumor and cancer therapy etc.
