Fabrication, characterization and photophysical investigation of organic and organic-inorganic nanoassemblies in aqueous medium

Abstract

Nanoscience, as the name suggests is an emerging area of science that involves the study of materials mainly in the nanoscale range. These materials exhibit a large range of novel properties because of their ultra-small size which makes them highly suitable for various kinds of applications. It is also a quickly growing field that can shape a new world around us and could lead to overwhelming development in fields that vary from manufacturing to health care. The range of nanoscale is considered to be around 1 to 100 nanometers. A nanometer (nm) is equal to 10-9 m (meter) or equal to 10-3 (µm) micrometer. We measure molecules and atoms in the scale of nm and µm. For example if we laid 10 hydrogen atoms side by side, it measures in nm scale, a strand of DNA has diameter 2.5 nm whereas the thickness of red blood cell is 7,000 nm wide. Nanotechnology, on the other side, is the drawing, manufacturing, and use of structures, devices, and systems at the nanoscale. So actually one is studying nanomaterials and their properties and the other is make use of those materials and properties to fabricate something new or different.
