フェムト秒レーザーを用いた複合ハイドロゲル微細構造の作製

抄録

By combining different type of monomers or hydrogels with varying molecular weights, a double-network hydrogel with strength much higher than those of single-network hydrogels could be achieved. In our study, microstructured hydrogel was fabricated inside another hydrogel, which has different molecular weight, by spatially selective photo cross linking, enabling the fabrication of hydrogel that has non-uniform distribution of stiffness. To confirm the hydrogel network, two separate hydrogels were bridged by lines of hydrogel structure fabricated between the hydrogels. This method can be used for new optical and/or bio applications.
