Abstract:
Acoustically activatable particles having low vaporization energy and methods for making and using same are disclosed. A particle of material includes a first substance that includes at least one 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 that remains a droplet 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.

Claim (Index 22):
A method of producing particles of materials for ultrasound activation, comprising:\n condensing, from a gaseous phase to a liquid phase, a first substance comprising at least one component that is a perfluorocarbon or perfluorochernical having a boiling point below 25\u00b0 C. at atmospheric pressure; extruding or emulsifying the first substance into or in the presence of a second substance to create a droplet having a diameter of less than one micron and in which the first substance is encapsulated by the second substance and wherein at least some of the first substance exists in the liquid phase at the time of encapsulation of the first substance within the second substance, and wherein the droplet is an activatable phase change agent that remains a droplet having a core that will remain in the liquid phase at a boiling point of the first substance and atmospheric pressure.
