Ultrasound has been used to trigger release of encapsulated material from polyelectrolyte
multilayer capsules. Sonication was found to destroy both plain and nanoparticle-modified
capsules. Cavitation occurs through the collapse of generated microbubbles and the
resulting shear forces should cause the destruction of the polyelectrolyte capsules.
Application in catalysis is demonstrated in this paper, while further potential usage of
ultrasound triggered release is anticipated in bio-medical applications.
