Nanomaterials are made of many different chemicals and compounds. Once formed, these materials are extremely small which give the nano product unique properties. There are four main classes of materials that are used to make nano sized products including metal, carbon , composites , and dendrimers. These products have a variety of applications and are used in the automotive industry, biomedical industry, in films, and much more. Nano scale material is unique because of its size, ranging from one nanometer to several hundreds of nanometers.
History of nanotechnology - Wikipedia
There are many water purifiers available in the market which use different techniques like boiling , filtration , distillation , chlorination , sedimentation and oxidation. Currently nanotechnology plays a vital role in water purification techniques. Nanotechnology is the process of manipulating atoms on a nanoscale. There are variety of techniques in nanotechnology which uses nano particles for providing safe drinking water with a high level of effectiveness. Some techniques have become commercialized. For better water purification or treatment processes nanotechnology is preferred.
