Combating Cancer: Microbubbles Cut Off Blood Supply and Help Deliver Drugs

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. Shown here is a gas embolotherapy scenario. After the droplets were injected intravenously with or without therapeutic agents (e.g., chemotherapeutics or genes) and subsequently transported to the tumor microcirculation by blood flow, bubble formation was induced by ADV on demand.
