The Emergence of Nanotechnology and its Applications

Nanotechnology deals with the application of nano-sized particles in the range of 1 to 100 nm, and due to their sizes they exhibit unique properties which enhance a wide range of utility in various field of application. This paper reported the application of nanotechnology in the areas of wastewater treatment, biomedical and drug delivery system as well as in semiconductors and electronics. It was reported that nanotechnology can be effective in the removal of pathogenic microorganisms as well as inorganic and organic pollutants from wastewater; also the use of nanotechnology was reported to be effective in biomedical and drug delivery system as well as in electronics and semiconductors.
