Abstract
Elastic protein microspheres, filled with water insoluble gases, have been produced by ultrasound and mechanical cavitation without the present of oxygen. The microspheres are highly echogenic. The microspheres exhibit greatly enhanced static pressure stability, up to 40 psig. The microspheres are resistant to coalescence and to expansion due to differential gas diffusion. The microspheres are resistant to collapse when suspended in a gas-depleted aqueous solution.
