(a–c) Measurement of Jurkat T-lymphocytes flowing (a) over a planar CPW with microchannel width of 10 μm and height of 100 μm, (b) over a planar CPW with microchannel width of 10 μm and height of 10 μm, and (c) through a T-CPW. The insets in the lower panels show the illustrated cross section of the microchannel when a T cell passes the sensing region. Since the cross sectional area of the cells is greater than that of the microchannel, the cells are squeezed, which is indicated by their deformed shape in the illustration. (d–f) Analysis of the peak shapes. The peak heights were normalized and the resulting peaks were layed on top of each other. Red curves represent measurement data, whereas the black curves represent an average over all individual peak shapes.
