Nanomaterial Dimmer Switch Modulates Brain and Heart Cell Activity Using Near...

Scientists have used nanoparticles embedded in collagen foam to modulate electrical activity in neurons of the brain and muscle cells of the heart. This non-genetic technology that modulates the activity of excitable cells through light, using biocompatible and biodegradable nanoparticles offers a minimally invasive method for controlling cellular activity and can serve as a valuable tool in nano-neuroscience and nano-engineering.
