Abstract– Nanotechnology is an emerging technology. Its significance lies in comprehension, use, and control of matter which lies at the level of almost atoms, with which to manufacture new substances, instruments and frameworks, It is also known as molecular manufacturing. It is an emergent diversity of technologies in which medicine and engineering come together with physical and chemical science and opening up many new possibilities. In a world increasingly concerned about climate change, resource depletion, pollution and water shortages, nanotechnology has been much heralded as a new environmental saviour. Its proponents have claimed that it will deliver different efficient, inexpensive and environmentally sound technologies. In short, nanotechnology will enable ongoing economic growth and the expansion of consumer culture at a vastly reduced environmental cost, since the use of smaller quantities of potent nanomaterials will break the tie between economic activity and resource use. However, the extent industrial and commercial use of nanomaterials affecting organisms and ecosystems is greatly debated. These include Potential risks such as environmental, health and safety issues; transitional effects such as displacement of traditional industries as the products of nanotechnology become dominant, military applications such as biological warfare and implants for soldiers and surveillance through nano-sensors. These may be particularly important if potential negative effects of engineered nanoparticles are overlooked before they are released.
Key words: Nanotechnology, Nanomaterials, Dose-response relationship, Antibacterial nano-silver, Nanotubes, Resource depletion, Environmental saviour, Domino effect
