Figure 4. Multi-channel recording of DNA translocation with three nanowire-nanopore FET sensors.

Figure 4

All measurements are made with 1 M KCl buffer in cis chamber and 10 mM KCl buffer in trans chamber, voltage of 3 V and 1.4 nM pUC19 DNA. a, Simultaneous recording of the total ionic current and three nanowire-nanopore FET conductance channels. b, Higher-resolution view of the multiplexed recording from dashed rectangular area in panel a. The dashed red trace in the upper panel corresponds to the reconstructed ionic current trace (offset 10 nA for clarity) calculated from the three FET traces.
