Nanoscale science and technology is a young and burgeoning field that encompasses
nearly every discipline of science and engineering. With rapid advances in areas such as
molecular electronics, synthetic biomolecular motors, DNA-based self-assembly, and
manipulation of individual atoms via a scanning tunneling microscope, nanotechnology has
become the principal focus of a growing cadre of scientists and engineers and has captured
the attention and imagination of the general public. This field is defined primarily by a unit of …
