Development of Ultrasound Microbubbles and Phase Shift Microbubbles in Theranostics. [PDF]

Wiley Interdiscip Rev Nanomed Nanobiotechnol
ABSTRACT Ultrasound is widely used for diagnostic imaging and therapy. Microbubbles (MB) are effective reflectors of ultrasound and cavitation enhancers, hence their roles in diagnostic and therapeutic ultrasound. MB must be of controlled size, concentration, biocompatible, and stable for biomedical use.
