Injectable Biosensors Convert Brain Activities into Detectable Optical Signals

Technology for monitoring neuronal activity noninvasively could allow scientists to study the brain without the need for surgery or implanted devices. The newly developed nanotechnology, called NeuroSWARM3 by its inventors at the University of California, Santa Cruz (UCSC), could even provide a bridge to more effective communication and interaction for those who are physically challenged. “NeuroSWARM3 can convert thoughts (brain signals) to remotely measurable signals for high-precision brain-machine interfacing,” professor Ali Yanik said. “It will enable people suffering from physical disabilities to effectively interact with [the] external world and control wearable exoskeleton technology to overcome limitations...
