Nanotechnology is the study of matter at the nanoscale and was first discussed by Richard Feynman in a 1959 speech at Caltech. Feynman talked about the possibilities of manipulating matter at the nanoscale. Today, nanotechnology is a rapidly growing field with applications in manufacturing, water purification, energy, medicine, food production, and infrastructure development. Nanotechnology also shows promise for enabling self-powered objects and more efficient energy harvesting from various environmental sources.
