The scope and application of nanotechnology is tremendous and mind-boggling. According to the scientists, 21st century would be the nanotechnology century. It is estimated that nanotechnology would revolutionize every area, be it medicine, aerospace, engineering, various industrial and technological areas, health or any other field. Nano biotechnology can make tiny medical devices and sensors with fantastic military and civilian use. Converting sunlight into power, targeting a drug to a single malignant cell, cleaning ponds and creating sensors in the form of biochip, to be interested in the human body are some of the important landmark breakthroughs of nanotechnology. The technology has the potential to produce garments which can block chemical and biological weapons from touching the skin of a person. Nanotechnology has many more applications. It can help detect narcotics and fingerprints of suspects in crimes. The technology can make canonized robots and repair damaged and diseased tissues. Nanobots may be made from carbon nano tubes used to carry out functions like human beings. Nano- coatings are transparent, scratch- resistant and dirt repellent. Thus, it is estimated that there will be no sector of industry which will not use nanotechnology in future.
