Application of Nanotechnology in Commercial field
Journal Title: Indian Journal of Research in Pharmacy and Biotechnology - Year 2016, Vol 4, Issue 6
Abstract
The materials which are processing to a grain size of a billionth of a meter are called nanomaterials or nanoparticles. The naturally occurring or the incidental byproducts of combustion processes are usually physically and chemically heterogeneous in nature and often termed as ultrafine particles Nanomaterials produced by an engineer are designed with very specific properties related to shape, size, surface properties and chemistry. These properties are reflected in aerosols, colloids, or powders. Often, the behavior of any nanomaterials may depend more on surface area rather than particle composition itself. However, relativesurface area is one of the principal factors that enhance its reactivity, strength and electrical properties. The 2000s have seen the beginnings of the applications of nanotechnology in commercial products, although most applications are limited to the bulk use of passive nanomaterials. Examples include titanium dioxide and zinc oxide nanoparticles in sunscreen, cosmetics and some food products; silver nanoparticles in food packaging, clothing, disinfectants and household appliances such as Silver Nano; carbon nanotubes for stain-resistant textiles; and cerium oxide as a fuel catalyst. As of March 10, 2011, the project on emerging nanotechnologies estimated that over 1300 manufacturer-identified nanotech products are publicly available, with new ones hitting the market at a pace of 3–4 per week. Nanotechnology is being used in developing countries to help treat disease and prevent health issues. The umbrella term for this kind of nanotechnology is Nanomedicine. Nanotechnology is also being applied to a variety of industrial and purification processes. Purification and environmental cleanup applications include the desalination of water, water filtration, wastewater treatment, groundwater treatment, and other nanoremediation. In industry, applications may include construction materials, military goods, and nano-machining of nano-wires, nano-rods, few layers of graphene, etc.
