Ultrasound And ‘Cages’ Get Drugs To Targets In Brain, Johns Hopkins University Study Reveals
Biomedical engineers are using pulses of ultrasound to help deliver tiny amounts of a drug to small targets in the brain.
The method—recently tested in rats—involves “caging” a drug with tiny biodegradable nanoparticles. When the particles reach the right place in the brain, precisely targeted high-frequency sound break them up and release the drug.
