The simulation of an oscillating bubble near various bio-materials (brain and cornea) using the Boundary Element Method (BEM) is presented. The bio-materials are modeled as an elastic fluid with different Young's modulus and density. It is found that the bubble tends to split into two or more bubbles when it is oscillating near soft bio-materials (such as brain). The bubble will collapse with a high speed jet (about 100 m/s) near hard bio-materials (such as cornea). It is found from simulation that under certain conditions (light and soft elastic material), the oscillating bubble will jet away from the elastic boundary similar to a bubble near a free surface. An experiment using a laser generated bubble is carried out to confirm this phenomenon.
