Cell patterning onto the printed protein array spots within a device using DEP. The protein spotted, the cells and staining are as in Fig. 2D. A: DEP cell patterning of single cells, cell pairs and a small group of cells around each electrode pair. B: Protein spots (green) with a single cell, cell pair and a small group of cells. The flow rate and electric field controlling DEP were decreased in (B) to allow an increased number of cells to be captured.
