What is Nanotechnology?
Nanotechnology involves the manipulation of
matter at the nanoscale—dimensions between approximately 1 and 100 nanometers. At this scale, materials exhibit unique properties that differ significantly from their bulk counterparts. These properties can be harnessed for a wide range of applications in industries such as electronics, medicine, and environmental science.
Why is Nanotechnology Important?
The significance of nanotechnology lies in its potential to revolutionize various fields. For example, in the realm of
medicine, nanotechnology enables the development of more effective drug delivery systems, diagnostic tools, and even treatments for conditions like cancer. In
electronics, it allows for the creation of smaller, faster, and more efficient devices. Environmental applications include the development of new methods for
pollution control and renewable energy solutions.
