Figure 2:  To redesign the cell-pairing device for immune cells, we have established a finite element fluids model. The plot shows the predicted effect of reducing cup spacing (normalized by the downscaled immune cell device) on the relative flow rate through the capture cups. The blue line represents the original cell fusion device. The green line represents simple downscaling of the original device, yielding low flow and, presumably, pairing efficiency. The physical limit (black line) indicates the smallest cup spacing possible that still permits cells to pass between two cups. The model shows that reduc¬ing the horizontal cup spacing can increase flow through the cups and, ultimately, pairing efficiencies for immune cells.
