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.
