Nanobubbles Deliver Targeted Cancer Drugs Using Ultrasound

A new targeted drug delivery method uses ultrasound to image tumors, while also releasing the drug from "nanobubbles" into the tumor, according to a study published online July 10 in the Journal of the National Cancer Institute. Cancer drugs can be targeted to tumors by delivering them in packets of nanoparticles, then releasing them with ultrasound. But this approach can be difficult because it requires a way to image the tumor prior to treatment. Natalya Rapoport, Ph.D., D.Sc., of the University of Utah in Salt Lake City and colleagues describe a new method of drug delivery that may address this problem. Nanobubbles filled with the chemotherapy drug doxorubicin were injected into mice. The bubbles accumulated in...
