1. What is nanotechnology?
On a comparative scale, if a marble were a nanometer, then one meter would be the size of the Earth
What is nanotechnology?
There are 25,400,000 nanometers in an inch
Nanotechnology is science, engineering, and technology conducted at the nanoscale, which is about 1 to 100 nanometers.
A sheet of newspaper is about 100,000 nanometers thick

2. Nanotubes & Applications
This material is highly elastic, environmental friendly, and light weight.
Currently it is used to build tennis racquets, baseballs, surfboards, etc.
Researchers from Rice University and State University of New York - Stony Brook have shown that the addition of low weight percent of carbon nanotubes can lead to significant improvements in the mechanical properties of biodegradable polymeric Nano composites for applications in bone tissue engineering.

3. Research
Researchers are trying to see if CNTs can be used to help bone tissue engineering.
They have found that CNTs can be used for the reinforcement of biomaterials to substitute hard tissues. The composites of CNTs and ceramics are mainly used for this purpose. Because these composites do not need to be degraded and contact with cells directly, it is not necessary to consider the toxicity.

4. Chemistry Concepts learned in Class
A single walled carbon nanotube is made up of a single layer of graphite rolled up into a seamless cylinder. Graphite is an allotrope, which we learned about in class. In graphite the carbon atoms are strongly (covalently) bound to each other. We learned about covalent and ionic bonds in class as. We are learning about dissolutions.
