How to visualize the fascinating world of nanotechnology? In this article, we will try to make it clearer and easier to understand where nanotechnology can be found. Nanotechnology is science conducted at the nanoscale, which is about 1 to 100 nanometers. It is even hard to imagine how small it is but imagine for example a sheet of newspaper – it is approximately 100,000 nanometers thick. Today’s engineers are searching a wide variety of ways to deliberately make materials at the nanoscale to take advantage of their benefits such as higher strength, lighter weight, increased control of light spectrum, and greater chemical reactivity than their larger-scale counterparts.
Nanotechnology can be found everywhere – for example, superfast computers with vast amounts of storage. Nanoscale materials are beginning to enable washable, durable “smart fabrics” equipped with flexible nanoscale sensors and electronics with capabilities for health monitoring, solar energy capture, and energy harvesting through movement. Safer food through packaging and monitoring; regrowth of skin, bone, and nerve cells for better medical outcomes; smart windows that lighten or darken to conserve energy; and nanotechnology-enabled concrete that dries more quickly and has sensors to detect stress or corrosion at the nanoscale in roads, bridges, and buildings.
Nanotechnology is helping to considerably get better and revolutionize many technologies and industry sectors.
