Ultrasound-Mediated Local Drug and Gene Delivery Using Nanocarriers
Figure 5
Ultrasound-mediated drug release from eLiposomes. (a) Under the action of low-pressure ultrasound, the droplet vaporizes and expands, breaking the bilayer membrane and leading to release of the contents; this expansion stretches and tears the bilayer membrane (b) or results in cracking into small pieces [23].
