Nanotechnology is the science of engineering microscopic particles to perform tasks on a cellular level. Some nanoscientists are developing microscopic machines to perform tasks in a world so small that the unassisted human eye is unable to watch. Various nano-fields have emerged: nanomedicine, nanoengineering, nanoagriculture, and many more. Scientists are making astounding discoveries on the nano scale level.
Nanotechnology is the study and development of particles and even machines on a cellular scale. A nanometer equals one-billionth of a meter. Nanoparticles are already being used in medicine and nanomachines are being developed to perform a variety of tasks. Nanotechnology will affect every part of our lives within the next decade.
Is Nanotechnology a threat or an opportunity?
Nanotechnology is the engineering of tiny particles, systems or machines. A nanometer is one-billionth of a meter, or about the width of three or four atoms. Scientists are developing machines so small that the naked human eye cannot see them.
The theoretical possibilities of nanotechnology were first envisioned in 1959 by renowned physicist Richard Feynman. The word nanotechnology was popularized in the 1980’s by K. Eric Drexler. The US National Nanotechnology Initiative was created to fund nanotechnology research.
