DOI: 10.1002/elps.201900097 The cover picture shows two arrays of three‐dimensional photoresist structures coated by Platinum and connected via buried bottom planar connections. The standing pillars extend from the bottom to the top of a 50 µm high microfluidic chamber, thus generating uniform electric field lines across the direction normal to the chip. Each pillar electrode is singularly connected, which allow to selectively trap single cells in flow inside each adjacent quadrupole and to make them rotate at constant speeds. The observation of speed induced by different electric field frequencies reveals in high resolution the dielectric properties of the cell.
