Nanomaterials - Small size &Big impact

Materials with any external dimension in the Nano scale or having internal structure or surface structure in the Nano scale. It has high surface to volume ratio hence very reactive. Bottom Up and Top down are the two methods for the preparation of nanomaterial.Nano Materials are designed for the benefits in various fields of applied Sciences and Engineering. These materials are Nano in size but have a big impact in the field of material science and engineering. Nano materials are smart materials with definite order of structures. Nanotech research involves practical applications in smart sensors and smart delivery systems and used as  Magnetic Nano devices, Nano-Biosensors, Nano switches and Optical biosensors. Few famous nanoparticles used in industries are monometallic, bimetallic, iron oxide, titanium dioxide and zinc oxide. Nanoparticles in sunscreen, cosmetics, some of the food products, used as chemical catalyst, very good adsorbents, Carbon Nanotubes for stain-resistive textiles, and cerium oxide as a fuel catalyst.
