Nanoparticles that Control Neurons
October 12, 2021 | Terry Sharrer
Engineers at “Washington University in St. Louis [are] using nanoparticles as heaters to manipulate the electrical activity of neurons in the brain and of cardiomyocytes in the heart. . . . [It is] a noninvasive technology that inhibits the electrical activity of neurons using polydopamine (PDA) nanoparticles and near-infrared light. The negatively charged PDA nanoparticles, which selectively bind to neurons, absorb near-infrared light that creates heat, which is then transferred to the neurons, inhibiting their electrical activity.” MORE
