ABSTRACT
Nanotechnology is defined as the design and fabrication of materials, devices and systems with control at nanometer dimensions. It is the study of extremely small structures, having size of 0.1to100nm. In this paper we present an introduction to the principles and advances made in the fields of nanoscience and nanotechnology including inventions, discoveries and design and study of molecular building blocks studied through nanoscience and applied in nanotechnology. Nanoscience is the study of systems in nanoscale and nanotechnology is the ability to systematically organize and manipulate properties and behavior of matter in the atomic and molecular levels. Through nanoscience and nanotechnology it has become possible to study and create very useful functional devices, materials and systems on the 1 to 100 nanometer (one billionth of a meter) length scale. The reasons why nanoscale has become so important are presented. An application of Nanotechnology in various fields such as health and medicine, electronics, energy and environment, is discussed in detail. Applications of nano particles in drug delivery, protein and peptide delivery, cancer are explained. Applications of various nano systems in cancer therapy such as carbon nanotube, dendrimers, nanocrystal, nano wire, nano shells etc. Are given. Nano pharmaceuticals can be used to detect diseases at much earlier stages.
