Define nanotechnology

What is a simple definition of nanotechnology?

: the manipulation of materials on an atomic or molecular scale especially to build microscopic devices (such as robots) Placing atoms as though they were bricks, nanotechnology will give us complete control over the structure of matter, allowing us to build any substance or structure permitted by the laws of nature. —

What is nanotechnology and its uses?

Nanoscience and nanotechnology are the study and application of extremely small things and can be used across all the other science fields, such as chemistry, biology, physics, materials science, and engineering.

What is nanotechnology and why is it important?

Nanotechnology is designed to provide a novel and improved approach to cancer diagnosis and treatment. Since biological processes, including events that lead to the development of cancer, occur on a nanoscale at the surface of and inside cells, nanotechnology offers many tools.

What is nanotechnology in chemistry?

Nanotechnology is the science of extremely small structures that generally measure less than 100 nanometers (nm). Chemically inert materials such as gold can become catalysts at the nanoscale, while others can conduct electricity more efficiently than non-nano forms.

Why do we need nanotechnology?

Nanotechnology is helping to considerably improve, even revolutionize, many technology and industry sectors: information technology, homeland security, medicine, transportation, energy, food safety, and environmental science, among many others.

What are advantages of nanotechnology?
