Hydrogel microfluidic encapsulation

Fig. 16 Fluorescence images of LIVE/DEAD assays of the L929 cells encapsulated for 4 days (a) in the miniaturized PMBV/PVA hydrogel formed in the microfluidic chip, and (b) in the bulk PMBV/PVA hydrogel formed in the 96-well microplate. Green fluorescence indicates live cells and red fluorescence indicates dead cells. Scale bar 100 pm...

To produce microgels that have a very large pore structure with a high internal fluid content, one can utilize cross-junctions in the microfluidics to encapsulate quantum dot metal cores into a hydrogel microcapsule with size distributions typically within 5 %. Using such techniques, it is possible to obtain microgel particles in the size range of 10-1,000 pm [3]. 

The main focus of research on temperature-sensitive hydrogels as microactuators in microfluidic devices has been on microvalves. Hydrogel actuators have a distinct advantage for microvalve applications since they are very soft and encapsulate dust particles encountered in microfluidic flows. Normally, these particles...
