Magnetic Nanoparticles Can Remotely Control Worms
Using magnetic nanoparticles, scientists have found a way to remotely control neurons and affect animal behavior. The nanoparticles, which are targeted to attach to cell membranes, heat up when exposed to a magnetic field. Researchers have demonstrated that the heat can open calcium ion channels in cells, activate neurons and even cause C. elegans worms…
