Magnetic Nanodiscs Enable Remote Magnetomechanical Neural Stimulation
Magnetite nanodiscs decorating axons extending from a sensory neuronal structure dorsal root ganglion in vitro revealed by scanning electron microscopy. Switching from the vortex to in-plane magnetization state enabled the nanodiscs to transduce torques to the membranes of mechanosensitive neurons and, thus, to trigger their activity via remotely applied magnetic fields.
