Scientists
have figured out a way to
control nanobots using a molecular device that was inspired by
the human brain. Sounds like the makings of a sci-fi
thriller.
The control device is only two billionths of a meter across and is
made from 17 molecules of the chemical duroquinone. The molecules
act as switches, much as how ones and zeros are used in
computers.
The idea was inspired by the parallel communication of glial cells
in our own brain. Glial cells are known as the glue that keeps our
nervous system together.
Scientists were able to control up to eight nano-machines with this
device. It may seem paltry right now, but a journey of a thousand
nanobots begins with eight, as Lao Tzu said. Well, maybe that's not
exactly what he said, but you get the idea.
The potential of such a discovery is exciting to say the least.
Aside from the blockbuster movies it would inspire, the technology
would be extremely useful in medicine. Imagine nanobots being able
to
combat tumors and diseases on command (sic 'em,
boys!).
