Manchurian
Future? Scientists Remotely Control
Neurons
And Animal Behavior
Clusters of heated, magnetic
nanoparticles
targeted to cell membranes can
remotely
control ion channels, neurons and even
animal
behavior, according to a paper
published by
University at Buffalo physicists in
Nature
Nanotechnology. The research could
have broad
application, potentially resulting in
innovative cancer treatments that
remotely
manipulate selected proteins or cells
in
specific tissues, or improved diabetes
therapies that remotely stimulate
pancreatic
cells to release insulin. The work
also could
be applied to the development of new
therapies
for some neurological disorders, which
result
from insufficient neuro-stimulation.
"By
developing a method that allows us to
use
magnetic fields to stimulate cells
both in
vitro and in vivo, this
research
will help us unravel the signaling
networks
that control animal behavior," says
Arnd
Pralle, PhD, assistant professor of
physics in
the UB College of Arts and Sciences
and
senior/corresponding author on the
paper.
