What is nanotechnology?
What is nanotech?
Nanotechnology is the science of manipulating matter at the
atomic and molecular level—typically less than 100 nanometers. To put this into
perspective, one nanometer is approximately 100,000 times smaller than a human
hair. At this scale, materials behave in ways that are impossible at larger
scales.
Nanotech Evolution till 2025
From its concept in the 80s, nanotechnology has become one
of the most powerful fields in science and technology. By 2025, nanotechnology
will be a practical commercial reality across multiple industries, spanning
medicine to renewable energy.
