| Research Abstract |
We developed microfluidic systems composed of photo-shrinkable hydrogel sheets, and demonstrated independent control of 10 microvalves and on-demand control of fluid mixing. Also we developed a photo-responsive hydrogel which returns from photo-induced shrinking state to the stable swollen state about 10 times faster than existing ones requiring more than 1 hour, and demonstrated photo-controllable micro-manipulation of small object on the hydrogel sheet. Further we developed a hydrogel functionalized with photo-acid-generating groups, and fabricated a photo-writable microfluidic chip which can be used in wide pH conditions.
