Hydrogel-Based Microfluidic Concentrator |
| 초록 |
Hydrogel-based microfluidic platform has been extensively investigated because it is easy to position at microfluidic system by photo-polymerization and can perform both sensing and actuation functions. Here we propose novel microfluidic concentrator system which is prepared by combining pH sensitive hydrogel microvalve with patterned polymeric inverse opal structure. To integrate the inverse opals on microfluidic chip, colloidal particles are crystallized on photocurable polymer thick film first. By using conventional photolithographic method, the colloidal crystals were patterned in micron scale then incorporated into microfluidic channel. Hydrogel valves could be fabricated by in situ photopolymerization in microfluidic channel. The concentrator system was actuated and tested with pH buffer solution to give sieve for concentrate the microscale analytes. Finally, hydrogel-based microfluidic concentrator system was applied to concentrate the micro-sized analytes. |
