Introduction to Nanotechnology

The prefix “nano” means one-billionth. Therefore, a nano-meter is one-billionth of a meter. A sheet of paper is about 100,000 nanometers thick!

New microscopes were created that can “see” things this small.

A whole new industry was created using materials that have at least one dimension that is between 1 and 100 nanometers thick. It is called “nanotechnology”.

The illustration below will give you an idea of the size that we are talking about. The man-made metallic “microspheres” being discussed on this site (that are currently being referred to as “coronavirus”) are about one-tenth of the size of the “red balls” below!

The red balls below, labeled as PM2.5, represent the smallest size particles that your body can filter out naturally. Breathing in particles smaller than this size can get deep into your lungs where you can’t get them out. These build up over time and interfere with your breathing.

( 1 micron = 1000 nanometers  . . .  2.5 microns = 2500 nanometers )


Our government has a few agencies and websites dedicated to this new technology. They have produced an incredible amount of documentation and reference information. Links to some of these websites are included in this section for your enlightenment.

Investigate for yourselves!
