What is Nanotechnology

I met a friend about 2 weeks back whom I've not caught up for about half a year. He has gone into a new nanotechnology business which was absolutely Greek to me :-) (However, it's good to learn something new once again.).

Essentially, with nanotechnology, comes products like steriliser which means NO MORE SMELLING SHOES, not just legs :-)

So, hey, isn't that good news? The next time you walk into a spa and they hand you some sandals to change into, just pray that it is using these products...Good Luck!

You can read about nanotechnology from his website at http://www.nanoworld.sg, of which here is an excerpt:

=== EXCERPT ===
What is Nanotechnology:

"Nanotechnology is a rapidly growing science of producing and utilizing nano-sized particles that measure in nanometers (1 nm = 1 billionth of a metre).

The term nano particle is generally used to indicate particles with dimensions less than 100 nanometers (one nanometer is one billionth of a meter). For comparison, a human hair is about 100,000 nm in diameter, while a smoke particle is about 1,000 nm in diameter.

The smallest nano particles, only a few nanometers in diameter, contain only a few thousand atoms. These particles, called quantum dots, can possess properties that are entirely different from their parent materials.It is the material improved economical efficiency of silver with its nano particles. Nano Silver is verified scientifically that it sterilizes about 650 kinds of bacteria and virus. Silver is also harmless to the human body.

It is broadly studied as a material for medical treatment of SARS, bird flu, swine cholera and super influenza.
Nano Silver has various functions of deodorization, anti-bacterial ability and reducing electromagnetic waves with high efficiency due to its ability to combine with the cell walls of pathogenic bacteria; it directly gets inside the bacteria and quickly combines with the sulphydryl (-SH) of oxygenic metabolic enzymes to deactivate enzymes, block inhalation and metabolism and suffocate bactera."
