For the first time in the history of science & technology, a revolution has occurred, based on the recently developed ability to measure and manipulate matter on the nanometer scale in a skillful manner. As a result progress in nanoscale will have far reaching impact and the next revolution in science and technology will depend on science interdependence. This technology would directly benefit a common man when it comes to commercial use and it has already established a beachhead in the economy.
We have discovered and explored a new bio-safe and bio-compatible route for the synthesis of oxide nanomaterials using water as solvent as well as source of oxygen. The use of water as a reagent is particularly attractive because it is safe, inexpensive, environmentally benign and bestowed with many virtues especially under supercritical conditions. The simple and straightforward route is based on simple reaction of water and metal powder at relatively low temperature. Since water is regarded as a benign solvent and non toxic, the product (nanostructures) could be used safely for biomedical and other applications. The structural and surface morphology has been ascertained by the versatile equipments. In addition, the method is simple, straightforward, economical, environmentally benign, involves green chemistry, which can make it suitable for scale large production. The prospects of the process are bright and promising. There are number of applications including medicine which shall be discussed during the talk.
