Experimental apparatus for ultrasound-triggered release (see text for details). This apparatus consists of a Costar transwell insert with 0.4 μm pore polyester membrane resting on a sheet of Rho-C rubber. Polyester membrane has a 100% of transmission ultrasound wave and Rho-C rubber eliminated the reflection of ultrasound wave. A thin layer of water was put between the membrane and the rubber to exclude air and air bubbles. The open top of transwell insert allowed for introduction of the liposome dispersion (400 μl) and placement of the ultrasound probe.
