Calcein release from decafluorobutane (DFB) PDLCs inside of a capillary after a single pulse train (300 cycles,1.85MPa, 1.1 MHz) (A) Schematic setup for visualizing calcein release in a capillary tube. (B) Fluorescent images of PDLCs before and after US exposure. An instant increase of fluorescence in the green channel shows the instant release of calcein inside of the capillary tube. This experiment was repeated on three independent samples.
