26 Nanosensors: Physical, Chemical, and Biological
A CNT, also called a buckytube, is a large molecule of pure carbon that
is long and thin and shaped like a tube, hundreds to thousands of nano-
meters long. It is 10
2
times stronger than steel and but has one-sixth its
weight.

Example 1.2
How many hydrogen atoms can be lined up end-to-end to make 1 nm length?
Since diameter of a hydrogen atom is 0.1 nm, 1/0.1 or 10 such atoms
will be necessary ...
