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 essay?
Nanotechnology is a part of science and technology about the control of matter on the atomic and molecular scale – this means things that are about 100 nanometres across. Nanotechnology includes making products that use parts this small, such as electronic devices, catalysts, sensors, etc.
What is the importance of nanotechnology?
Nanotechnology is designed to provide a novel and improved approach to cancer diagnosis and treatment. Nanoscale devices can interact with large biological molecules on both the surface and inside cells involved in cancer.
Is nanotechnology safe for the environment?
Nanotechnology has direct beneficial applications for medicine and the environment , but like all technologies it may have unintended effects that can adversely impact the environment , both within the human body and within the natural ecosystem.
Who uses nanotechnology?
Nanotechnology is being used in developing countries to help treat disease and prevent health issues. The umbrella term for this kind of nanotechnology is Nano-medicine. Nanotechnology is also being applied to or developed for application to a variety of industrial and purification processes.
What nanotechnology means?
Nanotechnology (or ” nanotech “) is the use of matter on an atomic, molecular, and supramolecular scale for industrial purposes. It is therefore common to see the plural form ” nanotechnologies ” as well as “nanoscale technologies” to refer to the broad range of research and applications whose common trait is size.
Who invented nanotechnology?
