Neuro-SWARM: System-on-a-Nanoparticle for Wireless Recording of Brain Activity

Abstract: A fundamental limitation of the implantable brain-machine interfaces (BMI) is the wiring requirements for power transfer and signal transmission. Existing microelectrode technologies can only record from localized sections of the brain and require implantation of invasive electrodes through cranial surgeries. Here, we introduce a system-on-a-nanoparticle probe, a Neurophotonic Solution-dispersible
