Nanotechnology defined as the handling of matter at the atomic and molecular level is rapidly transforming several disciplines. At the moment, it enriches medicine as it offers specific delivery of drugs, which increases the effectiveness of the treatment and reduces the impact on the organism. Nanoparticles help in the early stage diagnosis of diseases in diagnostics and nanomaterials assist tissue engineering in regenerative medicine. In electronics, nanotechnology has made products compact, fast, and efficient including; advanced semiconductors and high-capacity batteries.

Nanotechnology is used environmentally for water purification through the process of nanofiltration and removal of pollutants. It also improves the renewable energy technologies such as better solar cells and strong, light and flexible materials for wind turbine.

Turning to the future, the nanotechnology has much bigger potential for changes. In medicine, it may create the situation where people can be treated individually many diseases that today have no cure. In electronics, it will gradually push for the continued shrinking of things and the increase of efficiency, which may also cause further developments in quantum computing. Environmentally, future inventions could relate to better catalyst with enhanced energy processes and efficient ways of trapping and storing carbon.

Altogether, one can state that nanotechnology has the possibilities to change the world making it healthier, more technologically developed and environmentally friendly revolutionizing basically all spheres of human life and responding to the world’s most crucial issues.
