Why Nanotechnology Is Important. It is hoped that nanotechnology can deliver a valuable set of research tools and clinically helpful devices in the near future. The National Nanotechnology Initiative expects new commercial applications to be developed in the pharmaceutical industry including advanced drug delivery systems, new therapies, and in ...

A simple thought experiment shows why nanoparticles have phenomenally high surface areas. A solid cube of a material 1 cm on a side has 6 square centimeters of surface area, about equal to one side of half a stick of gum.

A nanoparticle of any material is a particle (per se) with spatial dimension (s) equal to or below ~ 100 nm; 1 nm = 1 billionth of a metre. The interest in nanoparticle research is because of the way materials behave so differently at the nanoscale, than at day to day (normal) dimensions.

Well, it turns out that nanoparticles – chunks of materials around 10,000 times smaller than the width of a human hair – may provide new and important solutions to many of the world’s problems. For example, new kinds of nanoparticle-based solar cells are being made that could, in the future, be painted onto the sides of buildings.

The term "nanoparticle" is not usually applied to individual molecules; it usually refers to inorganic materials. Ultrafine particles are the same as nanoparticles and between 1 and 100 nm in size, as opposed to fine particles are sized between 100 and 2,500 nm, and coarse particles cover a range between 2,500 and 10,000 nm.

2 What Are Small Particles and Why Are They Important? ... how this occurs, even after decades of research. Furthermore, little is known about how the particles then grow into nanoparticles. Because of their size, nanoparticles have a high surface-to-volume ratio, which means that the properties of the particles, in terms of their chemistry and ...

Nanoscale science and technology, often spoken of as “nanoscience” or “nanotechnology,” are simply science and engineering carried out on the nanometer scale, that is, 10 −9 meters. Figure 1.1 provides some sense of how this scale relates to more familiar, everyday scales. In the last two ...

Nanoparticles have one dimension that measures 100 nanometers or less. The properties of many conventional materials change when formed from nanoparticles. This is typically because nanoparticles have a greater surface area per weight than larger particles which causes them to be more reactive to some other molecules.
