FIG. 2.

Hydrodynamic cell patterning. (a) H1568 cells stained with CellTracker (red) at a concentration of approximately 2 million cells/ml are patterned onto the gelatin microdomain via immunoaffinity capture. (b) The distribution for the number of H1568 cells on each pattern (n = 100) with three different trials (error bars indicate the standard deviation) shows an average pattern size of 3.23 ± 1.84 cells/pattern. (c) The efficiency of the patterning method using immunoaffinity is 92.9 ± 6.2%.
