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…show more content…
Nanotechnology's impact on the ICT industry would increase as smaller processing chips are produced. "What we are proposing is a new type of computing architecture that is only based on nano mechanical elements," said Professor Robert Blick of the University of Wisconsin-Madison. As the chips get smaller and more powerful, computers will also shrink in size. Some can be as small as bacterium, while having a large storage capacity. However, engineers are finding that mechanical fans can't cool down the chips fast enough or are too big for the device. The smaller you make your devices, the more electrons rush through and the hotter your device gets," said Professor Blick. Heat is now the major factor limiting the size of laptops. Military weapons can be advanced further, with miniaturized weapons, bullets that can be programmed to strike specific targets, and clothes can be able to store energy to deliver 'superhuman strength', such as jumping over a wallwith ease. Despite all the incredible possibilities that nanotechnology provides, there are still limitations to it. While nanotechnology seems to be capable of creating everything, there are physical limits that all technology would stay within. The technology does not have immunities or miraculous powers that allow it to do absolutely anything possible. The nature will not be changed, and nanotechnology will definitely not
