Why Nanoparticles and Nanotechnology ?

Nanotechnology is a recent, revolutionary development in Science and Engineering. It aims at manipulating atoms, molecules, and nanometer-sized particles containing a few hundred to thousands of atoms with the goal of creating new materials, devices, or even molecular machines. Nanotechnology is widely considered to be one of the main forces driving the next major industrial and social revolution of the 21st century. It will likely impact virtually all areas of the physical sciences, biological sciences, and health sciences.

Nanoparticle research seeks to exploit the strong size dependence of the physical and chemical properties of nanometer-sized particles. Properties are usually significantly different from those of isolated atoms or molecules and from bulk material. This opens up the opportunity, for instance, to create materials and devices with entirely new properties.
