A new technique developed by Elisa Konofagou, associate professor of biomedical engineering and radiology at Columbia Engineering, has demonstrated for the first time that the size of molecules penetrating the blood-brain barrier can be controlled using acoustic pressure--the pressure of an ultrasound beam--to let specific molecules through. This innovative method, published in the Journal of Cerebral Blood Flow & Metabolism, may help improve drug delivery to the brain.
