Blowing bubbles for cancer treatment

(American Institute of Physics) Embolization — the use of various techniques to cut off the blood vessels that feed tissue growth — has gained traction over the past decades to treat cancerous tumors, and one specific version is gas embolotherapy. During this process, the blood supply is cut off using acoustic droplet vaporization, which uses microscopic gas bubbles induced by exposure to ultrasonic waves. Researchers have discovered that these bubbles could also be used as potential drug delivery systems.
