Abstract
An acoustically activatable particle of material includes a first substance that includes a component that is a gas 25° C. and atmospheric pressure. A second substance, different from the first substance, encapsulates the first substance to create a droplet or emulsion that is stable at room temperature and atmospheric pressure. At least some of the first substance exists in a gaseous phase at the time of encapsulation of the first substance within the second substance to form a bubble. After formation of the bubble, the bubble is condensed into a liquid phase, which causes the bubble to transform into the droplet or emulsion having a core consisting of a liquid. The droplet or emulsion is an activatable phase change agent having a core consisting of a liquid at 25° C. and atmospheric pressure. The first substance has a boiling point below 25° C. at atmospheric pressure.
