What is Nanotechnology?



     A basic definition: Nanotechnology  is the study of manipulating matter on an atomic and molecular scale. This covers both current work and concepts that are more advanced.
     In its original sense, 'nanotechnology' refers to the projected ability to construct items from the bottom up, using techniques and tools being developed today to make complete, high performance products. it allows scientists to create, explore, and manipulate materials measured in nanometers (billionths of a meter). Such materials can have chemical, physical, and biological properties that differ from those of their larger counterparts. 
       It means that, nonatechnology is already part of our daily life. It manipulates a lot of things  the sciences, medicine, agriculture, and industry because a material’s properties at the nanoscale can be very different from those at a larger scale. As reports of new discoveries and applications for nanotechnology emerged, governmental, industrial, and public stakeholders recognized the need to develop a standard nanotechnology terminology to facilitate communication among the various communities. Nanotechnology is now use in cancer treatment, used in clothing are stain-resistant pants and shorts with built-in sunscreen. Examples of agrifood research include developing bacterial pathogen detectors from nanochemicals for use post-harvest. Most science and technology experts consider nanotechnology to be an industrial revolution on the horizon that will have an enormous social and economic impact.
      Therefor NANOTECHNOLOGY is very useful in our daily activitiesand needs, but in every positive there is always a negative side. These means that nanotechnology produces also a side effects in humanlife, it helps to produce a bomb that is more explosive, that can kill a lot of innocent people.
