The Hong Neurotechnology Lab at Stanford University developed ultrasound-activated nanoscopic light emitters (mechanoluminescent nanoparticles) that are delivered via the blood stream, unlike conventional optogenetics approaches that require invasive fiber optic implants.
Stanford researchers have proposed a novel, in vivo, real-time epifluorescence imaging method in the second near-infrared region using single-walled carbon nanotubes (SWNTs).
