Nanotechnology is already making new materials available that could revolutionize many areas of manufacturing. For example, nanotubes and Nano particles, which are tubes and particles only a few atoms across, and aerogels, materials composed of very light and strong materials with remarkable insulating properties, could pave the way for new techniques and superior products. In addition, robots that are only a few nanometers in length, called Nano-bots, and Nano-factories could help construct novel materials and objects.In 2021, MIT's Department of Materials Science and Engineering (DMSE) announced that they have developed a new class of artificially created 2D molecules that spontaneously assemble Nano-ribbons that are stronger than steel. Previous attempts to create Nano-ribbons had always been dependent on biological processes which would break down over time. These new molecules don't break down, even when they are outside of water.Nanotechnology may transform the ways in which we obtain and use energy. In particular, it's likely that nanotechnology will make solar power more economical by reducing the cost of constructing solar panels and related equipment.
