Nanotechnology is the manipulation of matter on a atomic, molecular, supramolecular. The ideas and concepts behind nanoscience and nanotechnology started with a talk entitled “There’s Plenty of Room at the Bottom” by physicist Richard Feynman at an American Physical Society meeting at the California Institute of Technology (CalTech) on December 29, 1959.
There are various fields in nanotechnology including surface science, organic chemistry, molecular biology, semiconductor physics, microfabrication. They all use a system of measuring called nanometers. which is one billionth of a meters(10^-9). Nanotechnology describes how discoveries at the nanoscale are put to work, especially by controlling the behavior of matter and building useful devices.
There are many uses of nanotechnology. One use of nanotechnology is in medicine is by inserting nanobots into the blood stream. Once the nanobots are in they bring food, heat, and drugs to cells. The nanobots are also attrached diseased cells and search for cancer cells. Another use of nanotechnology is "nanosponges" which absorb toxins and remove them from the bloodstream. The nanosponges are polymer nanoparticles coated with a red blood cell membrane allowing them to move freely through the blood stream.
There are uses for nanotechnology in food. Like Nanosized additives specifically developed or are under development for feed include nanomaterials that can bind and remove toxins or pathogens for animal feed.Or a number of nanostructured food ingredients and additives understood to be in the R&D pipeline; eg. mayonnaise for a better taste and less fat use.
