Stimuli responsive hydrogel microtubes fabricated using microfluidic devices |
| 초록 |
We have prepared multi-stimuli responsive hydrogel microfibers and microtubes based on alginate templating method using microfluidic device. The hydrogel monomer solution containing N-isopropylacrylamide with sodium acrylate or allyl amine were irradiated with UV for in situ photo-polymerization. The responsiveness of prepared microtubes was observed using confocal laser scanning microscope by adjusting the pH or temperature of the medium. Repulsion force in polymer chains caused by protonation or deprotonation of amine group or acrylate group induce the change of diameter and wall thickness depending on the pH of medium. Furthermore, we could fabricate the bilayer hollow microfibers with developed microfluidic devices. |
