(a) Representative data of current readout for 7 μm diameter beads flowing through the micropore for single electrode open circuit sensing architecture. Peaks of various sizes result from single beads and bead aggregates of varying numbers flowing through the pore. The asymmetry of the positive and negative peaks for each event is due to beads travelling off axis and also imperfect alignment of the sensing electrode to the center of the pore(with DI water as buffer solution). (b) Zoomed in view of representative data of a single bead passing through the micropore.
