Outline of Final Research Achievements

Using the physical property measurement system completed in FY2020, we measured various mechanical parameters of biogenic materials. First, we applied chemical treatments such as ethanol and glutaraldehyde to porcine pericardium purchased from a supplier for a short period of time and compared the physical properties with those of untreated raw pericardium. Specifically, the following physical properties were measured: 1) burst pressure, 2) thread hooking strength using vascular sutures, 3) rupture strength, 4) elastic modulus, 5) tensile strength of the membrane cut into strips, 6) elasticity of the membrane, 7) elasticity of the membrane, 8) elasticity of the membrane, and 9) elasticity of the membrane in the presence of glutaraldehyde. We have completed a system that can measure parameters such as maximum length at break in accordance with ISO standards. We plan to apply this system to optimize the physical properties of various biomaterials by evaluating their physical properties.
