Abstract

A cavitation system was found in solid microcapsules with a membrane shell and a liquid core. By simply treating these microcapsules with hypertonic solutions, cavitation could be controllably triggered without special equipment or complex operations. A cavitation-formed vapor bubble was fully entrapped within the microcapsules, thus providing an advantageous method for fabricating encapsulated microbubbles with controllable dimensions and functional components.
