Ultrasound-Triggered Release from Multilayered Capsules

Abstract

original image

Sound effects: Multilayered capsules, such as that shown in the SEM image, are promising vehicles for the delivery of macromolecular drugs. Ultrasonic irradiation can be used to trigger the release of encapsulated species from capsules fabricated using layer-by-layer technology. Ultrasound affects the integrity of the capsule membrane, which leads to destruction of the entire capsule and release of the contents.
