What is Nanotechnology?
-The branch of technology that deals with dimensions and tolerances of less than 100 nanometers, esp. the manipulation of individual atoms and molecules.
How did it begin?
The ideas and concepts behind nanoscience and nanotechnology started with a talk entitled “There’s Plenty of Room at the Bottom” by physicist Richard Feynman at an American Physical Society meeting at the California Institute of Technology (CalTech) on December 29, 1959, long before the term nanotechnology was used. It wasn't until 1981, with the development of the scanning tunneling microscope that could "see" individual atoms, that modern nanotechnology began.
Just how small is the Nano?
- A sheet of paper is about 100,000 nanometers thick.
- A human hair is approximately 80,000- 100,000 nanometers wide.
- One nanometer is about as long as your fingernail grows in one second.

Nanotechnology and Medicine!
One application of nanotechnology in medicine currently being developed involves employing nanoparticles to deliver drugs, heat, light or other substances to specific types of cells (such as cancer cells). In the future, patients may have the opportunities to drink fluids that attack viruses and even slow down the aging process.
