Physicist Richard Feynman Is Called The Founding Father Of Nanotechnology. Nanotechnology is characterized as the research and utilization of structures between the range of 1 nanometer and 100 nanometers in size. To get an idea how small the structures are, for instance, to coordinate the width of a human hair, it will need about eight hundreds of 100 nanometer particles next to each other. Nano technology deals with different fields of science which include biology, chemistry, materials science, physics, and engineering. Into History The concepts and ideas backing the nanotechnology and nanoscience began with a discussion entitled "There's Plenty of Room at the Bottom" by the physicist Feynman at a meeting of American Physical Society held at the Institute of Technology in California (CalTech) on December 29, 1959, sometime before the expression nanotechnology was utilized. In his discussion, Feynman portrayed a procedure in which researchers would have the ability to control and manipulate single molecules and atoms. Over 10 years after the fact, in his research of the ultraprecision machining, Prof. Norio Taniguchi used the expression nanotechnology. It was not until the year 1981, with improvement of the microscope for scanning tunneling that might "see" a single atom that is when modern nanotechnology started. Applications in Modern World Nanotechnology finds wide range of applications in the modern world. The applications are not limited to a particular filed they are spread to very filed that is known today. Some of the applications are; • Medicine Scientists are creating modified nanoparticles of the molecule size that can convey medicines directly to infected cells in human body. When the procedure is perfected, it ought to significantly decrease the damage treatment, for instance, chemotherapy does to a healthy cells of patient. • Electronics Nanotechnology holds the answers for how we may expand the abilities of electronic gadgets and we decrease their power consumption and weight. • Food Nanotechnology is affecting some features of food science, from growth of food to packaging of food. Organizations are creating nanomaterials that will have any kind of effect on the food taste, as well as in food security, and the medical advantages delivered by the food. • Fuel Cells Nanotechnology is being utilized to diminish the expense of catalysts utilized in the fuel cells to create hydrogen ions from the fuel like methanol and to enhance the productivity of membranes utilized in the fuel cells to isolate hydrogen ions from different gases like oxygen. • Space Nanotechnology can hold the way to making more practical the space-flight. Progressions in nanomaterials make spacecraft light in weight and cable for the space lift conceivable. By essentially lessening the amount of fuel required for rocket, these developments could bring down the expense of space travel and reaching orbit. • Other applications are Solar Cells, Batteries, Fuels, Better Air Quality, Chemical Sensors, Cleaner Water, Sporting Goods and Fabric.
