‘Nanotechnology’ is actually a fairly new idea .Nanotechnology is engineering, science, and technology which is conducted on nanoscale .It is the manipulation of matter on an atomic and molecular scale.It is applicable in all the fields of science such as Biology, Materials science ,Physics and Engineering . Nanoscience involves the ability to examine and to control individual atoms and molecules .Scientists currently match the future implications of nanotechnology.Nanoscience or Nanotechnology is able to create many new materials and devices with a vast range of applications.
On the other hand , it raises many problems as any new technology including concerns about toxicity and environmental impact of nanomaterials ,and their effects on global economies . Nanorobotics center on self-sufficient machines which operate at nanoscale . There are hopes for applying nanorobotics in medicine ,yet it may not be easy to do such things because of drawbacks of such devices .Scientists on the moment have actually found that some of nanoparticles on which they are working can go through human skin .This could permanently damage our skin cells , causing cancer. If we are using nanoscience in everyday life in future , then it could affect the environment very much , so we don’t have that much advanced facilities to stop nanoparticles from going through them .Nanotechnology can make our life luxurious , but we may even lose an identity as humanity .
