Advanced Nanoscience and Nanotechnology

Nano Science and Nano Technology

Nano science and nanotechnology are the research and application of very small things and can be used beyond all the other science areas, such as chemistry, biology, physics, materials science, and engineering. Nanotechnology is the use of matter on an atomic, molecular, and supramolecular scale. Nanoscience is the subject of structures and materials on the measure of nanometers. To give you a concept of how long a nanometer is, this printed page is about 75,000 nanometers thick. When structures are made small sufficient—in the nanometer size range—they can take on interesting and valuable resources.

Nanoscale structures have lived in nature long before scientists started studying them in laboratories. A particular strand of DNA, the structure block of all living things, is about three nanometers wide. The systems on a morpho butterfly’s wings include nanostructures that transform the way light waves interact with each other, giving the wings sparkling metallic blue and green hues. Peacock feathers and soap bubbles also get their shimmering colouration from light interacting with structures just tens of nanometers thick. Scientists have even created nanostructures in the laboratory that simulate some of nature’s wondrous nanostructures.
