Nanotechnology is science, engineering, and technology conducted at the nanoscale. This is at a measurement ranging from about 1 to 100 nanometers. Nanoscience and nanotechnology are the study and application of extremely small things. Applications of Nanotechnology are broad and span many fields including: chemistry, biology, physics, materials science, and engineering. The ideas and concepts behind nanoscience and nanotechnology are first credited 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) in 1959. read more
