A new method for precision drug delivery: painting

Researchers are integrating ultrasound imaging with ultrasound therapy to pave the way for a new kind of drug delivery

If traditional drug delivery were a type of painting, it might be akin to paintball. With good aim, a majority of the paint ends on the bullseye, but it also drips and splashes, carrying streams of paint across the target.

If the drug needs to enter the bloodstream and circulate throughout your body for treating disease wherever it may be, this paintball-like delivery system may work. But it won’t work for targeted and precise drug delivery.

A more acute delivery approach would look more like “painting by numbers,” a technique that would allow precise delivery of a certain amount of drugs to an exact location. Researchers at the McKelvey School of Engineering and the School of Medicine at Washington University in St. Louis are developing the tools necessary for such a drug delivery system, which they call cavitation dose painting.
