What is Nanotechnology?
Nanotechnology is an area of science and technology that focuses on the designing, manufacturing, and management of materials on an extremely small scale, typically ranging from 1 to 100 nanometers. This field uses techniques and tools from physics, chemistry, biology, and engineering to develop and analyze nanoscale materials. The unique features of nanoparticles can be used for a wide range of applications in the healthcare sector.
Nanotechnology is used in healthcare in a variety of applications, including medication administration, imaging, and illness detection. The technology allows for the creation of nanoscale materials capable of targeting specific cells or tissues in the body, allowing for more effective and focused therapy. Nanotechnology also aids in the development of new materials capable of detecting diseases at an early stage, allowing for more effective and less invasive therapy.
Potential Applications of Nanotechnology in Healthcare
