Recent data suggest that increased circulation of cerebrospinal fluid (CSF) to clear the brain and spinal cord of waste is associated with improved outcomes in aging and recovery from brain injury, suggesting that inducing CSF clearing could enhance brain resilience. However, a therapeutic modality for directly inducing CSF clearing has not been available.

We propose to design a lightweight, wearable system for integrated ultrasonic drug uncaging and fUS neuroimaging to noninvasively pharmacologically modulate a brain target and then image the resultant changes in neural activity without significant motion limitations.

Developing a platform of biocompatible nanoparticles that uncage a drug payload upon ultrasound application.
