From: Nanopore Detector based analysis of single-molecule conformational kinetics and binding interactions
The channel current blockade signals observed in the prototype study (from [9]). Panel (a) shows the five DNA hairpins, with sample blockades, that were used to test the sensitivity of the nanopore device. Panel (b), top, shows the power spectral density for signals obtained from the different nine base pair DNA hairpins, as well as the open channel. Panel (b), bottom, shows the dominant blockades, and their frequencies, for the different hairpin molecules in panel (a).
