1 As the world of electronics become smaller, nanoparticles are important components in chip design. Two big applications are in petroleum refining and in automotive catalytic converters. Nanocatalysis - the use of nanoparticles to catalyze reactions - is a rapidly growing field which involves the use of nanomaterials as catalysts for a variety of homogeneous and heterogeneous catalysis applications.

The properties of many conventional materials change when formed from nanoparticles.

The 2000's have seen the beginnings f the applications of nanotechnology in commercial products, although most applications are limited to the bulk use of passive nanomaterials.Examples include titanium dioxide and in sunscreen, cosmetics and some food products; silver nanoparticles in food packaging, clothing, disinfectants and household appliances such as Silver Nano; carbon nanotubes … Nanoparticles are used increasingly in catalysis to boost chemical reactions.

The characterization of nanoparticles is a branch of nanometrology that deals with the characterization, or measurement, of the physical and chemical properties of nanoparticles.Nanoparticles measure less than 100 nanometers in at least one of their external dimensions, and are often engineered for their unique properties. Some of them are useful for a variety of applications such as catalysts, electronics, optics, biosensors, as well as magnetics.

In particular, compared to other nanoparticles, silver and gold nanoparticles based applications elicited beneficial results … Nanoparticles have been intensively studied in the past several decades because they have unique properties depending on their size.

This reduces the quantity of catalytic materials necessary to produce desired results, saving money and reducing pollutants. Heterogeneous catalysis represents one of the oldest commercial practices of nanoscience; nanoparticles of metals, semiconductors, oxides, and other compounds have been …

The range of applications for gold nanoparticles is growing rapidly and includes: Electronics - Gold nanoparticles are designed for use as conductors from printable inks to electronic chips.

Nanobiotechnology, bionanotechnology, and nanobiology are terms that refer to the intersection of nanotechnology and biology.
A nanoparticle is incredibly small, having one dimension that measures 100 nanometers or less, it would take eight hundred 100 nanometer particles side by side to match the width of a human hair. Metal nanoparticles can be obtained by physical and chemical processes.
