109 マイクロチャネルにおける微小液塊生成とその流動場の可視化(S33-1 マイクロチャンネル要素,S33 マイクロ・ナノフルイディクス)  [in Japanese] 109 Visualization Method for Cylindrical Droplet Formation in Microchannel  [in Japanese]

A novel cell encapsulation method in microchannel was studied. We used W/O emulsion in the rectangle microchannel fabricated by soft MEMS process. The cell encapsulation process and internal flow of the droplet were visualized. The velocity of the droplet and the cell were measured by the use of the digital image processing. Simple model for prediction of the all velocity was proposed. The theoretical result agreed well with the experimental data.
