Nano Technology, Today and Tomorrow
Nanotechnology, as we know, is an umbrella term used to define technologies working on nanoscales for utilization in this transformed world. Nanoparticles (NPs), the basic parts of nanotechnology, are atomic or molecular aggregates with sizes varying from 1nm to 100nm. In Nanoscience, we manipulate matters at their atomic or molecular level and discover a whole new material with properties totally different from the mother matter or more powerful than it. The world is facing significant changes in day to day life, be it with the environment, medical sector, automobile sector or any other field and to cope with these, Nanoscience or Nanotechnology is the need of the hour. In today's world, thinking of any innovation sans Nanotechnology is impossible. Nanoparticles can be synthesized either chemically or biologically, naturally or artificially. In this particular technology, we repair control, construct and monitor at the molecular level of any systems. Nanoparticles are of different types according to the size, morphology, physical and chemical properties. Some of them are carbon-based nanoparticles, ceramic nanoparticles, metal nanoparticles, semiconductor nanoparticles, polymeric nanoparticles. Nanotechnology has its impact in every field like medicine and with devices based on new technology, it can cure diseases, enhance the military with updated weapons, preserve our environment with new techniques to purify water, soil, gases and energy. Thus Nanotechnology, along with nanoparticle, is the only science that can control and conquer the world with its positive impacts on every aspect ranging from medical, ethical, environmental domains, to fields such as biology, engineering, material science and so on. It remains an answer to every question.
