| Outline of Final Research Achievements |
In this investigation, to make structure of 3D living tissue in vitro or in vivo, special microcapsules composed of a gas bubble, cells, and cultivation liquid were developed, which can be disintegrated and make stimulus to internal cells by controlling the strength of shock waves. It was concluded that (1) the microjet induced disintegration occurred when gas/liquid ratio was 30-40% by observing deformation process of a bubble in a capsule under microscopy, (2) the oscillation amplitude of a bubble increases when the gas/liquid ratio was small by analyzing special simplified mathematical model, and it corresponded to the observation results.
