Thin-shell encapsulated microbubbles (EMBs) are gas-filled microbubbles encased in a stiff albumin or flexible lipid shell. They have been shown to improve the performance of biomedical procedures such as ultrasound contrast imaging, targeted drug delivery and sonoporation.

The viscoelastic fluid will be modelled using models such as the Oldroyd B model while the properties of the shell are accounted for through the dynamic boundary condition at the bubble surface.

An interdisciplinary approach combining models for cell mechanics with bubble dynamics will provide insights into the deformation of cellular entities subject to cavitation flow and to enhance drug delivery via coated microbubbles. Ultrasonic cavitation is one of the most effective cleaning agents. For example, it is used to clean and to disinfect surgical instruments in hospitals. There is a wide range of other biomedical applications that will benefit from the computational models developed in this project.
