With Magnetic Nanoparticles, 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.

"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.
