WELCOME TO NANOWORLD

“Nano” is a prefix attached to words to denote a quantity one billionth of that represented by the words. In science and technology we generally use nanometer as the linear dimension one billionth of a meter. It is a very small length indeed! Atoms of many elements have diameters ranging from 0.1 to 1 nanometer. Scientists have discovered that matter exhibits strange and often beneficial properties when their dimensions are reduced to the nanometer levels. Many uses have been envisaged for such small materials. Superior mechanical properties, electrical properties and magnetic properties have been detected in many nanomaterials. In the medical profession, nanomolecules could be used to deliver medication to an exact location, like a tumor, in the human body. Structures and devices of nanometer size have been thought of for various applications. Nanomaterials, nanostructures and nanodevices occupy the nanoworld. This blog is intended to collect and present new developments in this nanoworld.
