New Technology Enables Precise Drug Delivery to Brain Using Ultrasound

The research results were published in on January 23, 2017, in the journal Nano Letters.

The new method could reduce the side effects of drugs considerable, because of the way it releases a much lower but concentrated dose a drug in a specific region. This results in a much lower overall drug doses for the patient during therapy treatment. The technology uses biomaterials, drugs approved by the US FDA, and ultrasound methods that have been tested, and found to be safe for humans. The researchers hope to start the regulatory approval process of their new technology for clinical applications within one or two years.

Associate professor of biomedical engineering, Jordan Green, PhD, said, "If further testing of our combination method works in humans, it will not only give us a way to direct medications to specific areas of the brain, but will also let us learn a lot more about the function of each brain area."
