In addition, we have demonstrated that imaging can be used to validate and track the delivery mechanism, "says Dr. Zheng, Senior Scientist at the Princess Margaret and also Professor of Medical Biophysics at the University of Toronto.
Conventional microbubbles, on the other hand, lose all intrinsic imaging and therapeutic properties once they burst, he says,
