Some microbiologists at the University of
Massachusetts Amhest have found a way to build electric wires that are
thousands of times thinner than a human hair and even environmentally friendly.
(They have a 1.5 nm diameter 60,000 times smaller than the human hair).
The secret?
"Microbiological nanotubes" or
filaments protein produced by genetic modifications in certain bacteria.
Scientists manipulate bacteria composing wires in heavy so very Nano small from
natural amino acids.
Dr. Derek R.Lovley, chairman of the team,
said that the wires can be produced easily and move because their material is
quite cheap.
It is believed that these wires widely
used in the medical field because they are biological and will not affect the
pH sensitive sensors used to measure the pulse of the heart or kidney function.
Surely one another very important use of
them will be in the field of telecommunications and informatics, where very
small size of the wires will allow for increasing memory capacity for mobile
phones and computers.
