Figure 3: Ionic current change caused by fd and dsDNA translocations.
From: Stiff filamentous virus translocations through solid-state nanopores
Histograms of the number of 4-μs-long samples of ΔIB per 3 pA bin (N), normalized by the total number of samples (Ntotal), for fd (panel (a), black, 280 translocations) and λ DNA (panel (b), grey, 1,434 translocations). The current recordings were performed on a 19-nm-diameter nanopore with V=100 mV in 100 mM KCl. The histograms represent currents recorded during translocation events and the 100 μs of baseline that preceded and followed each event. In 100 mM KCl, fd virus translocations caused the current to decrease, whereas λ DNA caused it to increase. Positive (negative) values of ΔIB due to baseline noise are omitted from the fd (λ DNA) histogram for clarity.
