In a new study researchers from the School of Biomedical Engineering & Imaging Sciences, in collaboration with the Noninvasive Surgery & Biopsy Laboratory led by Dr. James Choi at Imperial College London, have found that applying rapid short pulses (RaSP) of ultrasound can non-invasively deliver liposomes to the brain, across the blood-brain barrier. This is a specialized barrier between the brain and blood which restricts the entry of molecules to the brain, including over 90 percent of drugs. Their results were published in the Journal of Controlled Release.
