Human-Blood-Vessel-Resembling Double-Walled Microtube Hydrogels Prepared by Triple Channels Microfluidic System |
| 초록 |
In this study, we prepared microtube hydrogels with poly(N-isopropylacrylamide) (PNIPAm) and poly(acrylamide) (PAAm) as the inner and outer wall respectively. Triple channels microfluidic device combined with alginate-templated photopolymerization was used to allow the preparation of two separated hydrogel walls. The different property of the hydrogel walls enables the microtubes to have the human blood vessel behavior. By increasing the temperature, the thermally active inner wall shrinks while the passive outer wall maintaining its position, which results in a higher flux. In addition, the hydrogel walls can be reversed to have a thermally controllable outer diameter with a stationary hollow center by simply swapping the injection position of the pre-gel solutions. This flexibility suggests that this method can be applied for various hydrogel monomers. |
