The Impact of Nanotechnology in Our Lives"Nanotechnology is science and engineering at the scale of atoms and molecules. It is the manipulation and use of materials and devices so tiny that nothing can be built any smaller." It refers to the use of materials with nanoscale dimensions, ranging from 1-100 nanometers. Nanotechnology impacts our lives today in many ways, such as economically, socially, environmentally, ethically, and more.
Nanotechnology is used broadly in many ones' daily life. Many sunscreens containing nanoparticles of titanium oxide or zinc oxide can absorb and reflect UV light, while being transparent and allowing visible let through. EnviroSystems, Inc. developed a mixture named nano-emulsion of nanometer-sized oil drops mixed with bactericide, used in swimming pools as disinfectants. The oil particles adhere to bacteria thriving in water, making the delivery of the bactericide more efficient and effective. Tennis racket manufacturers introduce highly engineered products. Babolat introduced the VS Nanotube Power racket in 2002, made out of high modulus graphite with carbon nanotubes.
They are 100x stronger than steel, yet one-sixth the weight. Nanotech tennis balls is made by coating the ball's inner core with 20 microns thick of layered sheets of clay polymer nanocomposites - each 1 nanometer thin, so that it remains playable for a long period of time.
Nanotechnology has the potential to have major impact on the environment. An oil spill can be made harmless by the use of nanobots. They have fingers built from nanotubes, which can manipulate the atoms in an oil spill to render it nontoxic. Because of their small size, nanoparticles have more surface available for chemical interactions. Nanoparticles are being studied so that they could remove or destroy toxic substances from the environment. Researchers at Lehigh University have used nanoscale particles for groundwater remediation. These particles are made of iron,
