We made spherical microbeads, which represent the red blood cells, by droplet formation method using microjunction. The microbeads had the diameter of 95・m and the variation coefficient of 7.8%. The refractive index matching of microbeads and surrounding fluid for PIV measurement was successfully conducted. As a result, the interaction between the rigid rotation motion of microbeads and surrounding flow was investigated quantitatively. The measurement of red blood cells was also conducted as a target for comparison. The difference of the motions between rigid sphere and red blood cell are investigated from the viewpoint of their geometry, structure and stiffness.

我们通过使用微孔的液滴形成方法制作了代表红细胞的球形微珠。微粒的直径为95℃，变异系数为7.8％。成功地进行了Microbeads和周围流体的折射率匹配。结果，对微头的刚性旋转运动与周围流动之间的相互作用进行了定量研究。还进行了红细胞的测量作为比较的靶标。从刚性球体和红细胞之间的运动之间的运动差异是从它们的几何形状，结构和刚度的角度研究的。
