NANOTECHNOLOGY

            Nanotechnology is the meeting place of various branches of science including physics ,chemistry and biology. Nanotechnology is the science of small things - in particular things that are less than 100 nm in size. The term “nanotechnology” was termed by Professor Norio Taniguchi of Japan. Nanomaterials are chemical substances or materials that are used at a very small scale -down to 10,000 times smaller than the diameter of human hair. This materials have noble characteristics such as increased strength,chemical reactivity or conductivity compared to the same material without nanoscale features. In the past decade innovations in our understanding of nanotechnology have enabled us to begin to understand and control these materials and properties in order to develop new functional and useful materials and devices. According to the great indian scientist , Dr. A.P.J Abdul Kalam “Nanotechnology will be the future with nanoscience developing nanomaterials and devices”.
           Nanotechnology is having an impact on various fields like medicine,
agriculture, electronics, biotechnology and engineering. In medicine, scientists
are developing customized nanoparticles of molecular size that can deliver drugs
directly to diseased cells in our body. Nanotechnology holds some answers for
how we might increase the efficiency of electronic devices,while we reduce their
weight and power consumption. Nanotechnology is helping to advance the use of arthroscope, by making them smaller than a strand of hair in the future.
Nanonephrology is a branch of nanomedicine and nanotechnology which uses nanomaterials for diagnosis therapy and management of diseases of the kidney. In future nanotechnology can also be used in the treatment of cancer.Nanotecnology may hold the key to making space flight more practicle,and canalso improve air quality by improving the performance of catalysts used to
transform vapours escaping from industries and vehicles into harmless gases.
          In addition this technology can help in ensuing cleaner water, bettersports equipments, improved fabrics as well as developing sophisticatedcommunicating devices in the military.
         We have entered the era of engineered nanomaterials and devices.
Nanotechnology is the new technical revolution and products resulting from it
will affect all areas of our economy and lifestyle.
