Nanotechnology
was first used by Norie Taniguchi from Tokyo Univesity in a 1974 conference to
describe semiconductor process such as thin film desposition and ion beam
milling exhibiting characteristics control on the order of a nanometer.
Nanotechnology gives people the ability to look closer to the nano world, where
lie the answers to many problems hard to be solved. For example, nanotechnology
improves chemical engineering by making chemical bonds tunable. By Scanning
Tunneling Microscope, scientists are able to experiment chemical substance in a
level of atom, which is exactly the same idea brought up by Richard Feynman
that “the principles of physics, as far as I can see, do not speak against the
possibility of maneuvering things atom by atoms”.
Another
application of nanotechnology is in the field of nano-medicine, which includes
nano-therapy and nano-treatment. One interesting example is that people can use
nanodots to tag certain disease within animal body, thus trace and identify how
the condition of disease evolve while during the treatment.
Engines of
Creation: The Coming Era of Nanotechnology is a
landmark in the history of nanotechnology. Drexler imagines a world where
the entire Library of Congress can fit on a chip the size of a sugar cube and
where universal assemblers, tiny machines that can build objects atom by atom,
will be used for everything from medicinal robots that help clear capillaries
to environmental scrubbers to clear pollutants from the air. In the book,
Drexler first proposes the gray goo scenario—his prediction of what
might happen if molecular nanotechnology were used to build uncontrollable
self-replicating machines.
Nanotechnology is the tool for scientist and artist to
create a whole new world beyond people’s imagination. It vastly expands the
potential of development of science and art, because now they could reach out
the hands in a tiny yet fascinating and profound domain.
