Cancer drug delivery made more potent with microbubbles

January 12, 2021

University of Leeds research has shown how microbubbles deliver powerful cancer drugs can be guided to the site of a tumor using antibodies. Microbubbles are small manufactured spheres half the size of a red blood cell and scientists believe they can be used to transport drugs to highly specific […]
