A VERSATILE BOTTOM UP APPROACH FOR THE SYNTHESIS OF TIN OXIDE NANOPARTICLES AND THEIR POTENTIAL.

Functional oxides are presently much investigated for their potential applications in various areas and Tin oxide appears particularly interesting when grown in nanometer range. A versatile and an economic technique have been developed for the synthesis of tin oxide nanoparticles, which does not require any substrate or surfactant. The technique is based on a simple reaction of tin and water at low temperature. The water is regarded as benign and safe solvent and the nanostructures so produced are biocompatible. This synthetic technique has the following advantages: First, the synthesis needs no sophisticated equipments since it is conducted at low temperature of 200°C under normal atmosphere. Second, the clean surfaces of the as-synthesized nanostructures can be readily functionalized for various applications since there is neither a capping reagent nor a substrate. Finally, the approach is nontoxic without producing hazardous waste. Therefore, the technique could be extended and expanded to provide a general simple and convenient strategy for the synthesis of nanostructures of other functional materials with important scientific and technological applications. The relative studies are in process and will be reported in forth coming publications. [ABSTRACT FROM AUTHOR]
