We are developing microcapsule suspension, which is expected to be used for absolute hemolysis evaluation instead of animal blood. In this report, we describe fractural characteristics of microcapsule suspension under fluid dynamical shear stress, which is generated by rotational shear stressor developed in our laboratory. We tested two types of microcapsule suspension. One has 100 micrometer diameter and polyurethane membrane, and the other has 10 micrometer diameter and melamine membrane. Fractural property of the former suspension was similar to that of bovine blood, whereas the later suspenstion showed different result. This tendency seems to be caused by the laminar/turbulent combined flow condition in the shear stressor.
