Figure 2.
Example i-t traces of 570-nm radius particle translocation events. Traces correspond to data obtained with a 433-nm radius pore. A background trace, in the absence of particles, is shown in (a). Particles (0.001 wt%) are driven into the pore using a pressure of −50 mmHg applied across the glass nanopore membrane (internal vs. external). Translocation events over a 60-s period are presented in (b). Expanded image of a single event is shown in (c). The open-pore current (io), resistive pulse peak height ( μi), and width at half-peak height (Δτ) are indicated on the figure.
