Encapsulation of eukaryotic cells in alginate using commercially available microtubing. Liquid alginate droplets with encapsulated cells enter from the left. A crosslinking agent (barium chloride, stained with green dye for visualization) enters from the top. Hydrodynamic interactions in the T-junction adds a fixed amount of crosslinking agent to each droplet. Throughputs of up to 20 droplets/second can be achieved.
