In nanotechnology, a particle is defined as a small object that behaves as a whole unit in terms of its transport and properties. It is further classified according to size: in terms of diameter, fine particles cover a range between 100 and 2500 nanometers, while ultrafine particles, on the other hand, are sized between 1 and 100 nanometers.

Targeted nanoparticles offer promising techniques for cancer treatment

Researchers in the laboratory of Mark E. Davis at the California Institute of Technology have been using small interfering RNA (siRNA), sometimes known as silencing RNA, to "silence" specific genes that are implicated in certain malignancies.

Gold nanoparticles used as a simple "litmus test" for mercury

With gold nanoparticles, DNA and some smart chemistry as their tools, scientists at Northwestern University have developed a simple "litmus test" for mercury that eventually could be used for on-the-spot environmental monitoring of bodies of water, such as rivers, streams, lakes and oceans, to evaluate their safety as food and drinking water sources.
