Abstract

In a nanopore sensor, a nanopore disposed in a support structure has a nanopore diameter and nanopore resistance, R. A fluidic passage, disposed in fluidic connection between a first fluidic reservoir and the nanopore, has a cross-sectional extent, along at least a portion of the fluidic passage length, that is greater than the diameter of the nanopore and that is less than the fluidic passage length. The fluidic passage has a fluidic passage resistance, R, of at least about 10% of the nanopore resistance, R, and no more than about 10 times the nanopore resistance, R. The nanopore is disposed in fluidic connection between the fluidic passage and a second fluidic reservoir. At least one electrical transduction element is disposed at the fluidic passage and electrically connected to produce an indication of electrical potential local to the fluidic passage.
