A new technique developed by Columbia University has demonstrated for the first time that the size of molecules penetrating the blood-brain barrier (BBB) can be controlled using acoustic pressure, the pressure of an ultrasound beam, to let specific molecules through.  The study is being hailed as an important breakthrough in getting drugs delivered to specific parts of the brain precisely, non-invasively, and safely, and may … Continue reading New non-invasive technique controls the size of molecules penetrating the Blood-Brain Barrier.
