Nanoscale

Nanoscale

Nanoscale (pronunciation: /ˈnænoʊˌskeɪl/) refers to a physical scale that is approximately 1 to 100 nanometers (nm) in size. The term is derived from the Greek word "nanos", meaning "dwarf", and the English word "scale".

Nanoscale objects, also known as nanoparticles, are smaller than microscale (10^-6m) objects and larger than atoms and simple molecules. At the nanoscale, many common materials exhibit unusual properties, such as remarkably lower resistance to electricity, higher strength, and higher reactivity. This is due to the increased relative surface area and quantum mechanical effects.

Nanotechnology

Nanotechnology is the application of nanoscale science, engineering, and technology to create new materials and devices with a wide range of applications. This includes medicine, electronics, biomaterials, and energy production.

Nanomedicine

Nanomedicine is a branch of medicine that applies the knowledge and tools of nanotechnology to the prevention and treatment of disease. It involves the use of nanoscale materials, such as biocompatible nanoparticles and nanorobots, for diagnosis, delivery, sensing or actuation purposes in a living organism.

Nanomaterials

Nanomaterials are materials with structural components smaller than 100 nanometers. They can be created through top-down engineering methods, such as etching and lithography, or bottom-up methods, such as self-assembly of molecules. Nanomaterials are used in a variety of products, from sunscreens and cosmetics to coatings, textiles, and electronics.

Nanoscale Science

Nanoscale Science is the study of phenomena and manipulation of materials at atomic, molecular, and macromolecular scales, where properties differ significantly from those at a larger scale. It involves scientists from many different disciplines, including physics, chemistry, biology, and engineering.
