Abstract
A nanopore sensor includes a nanopore disposed in a support structure with a nanopore diameter and having a nanopore fluidic resistance, R. A fluidic passage, is disposed in fluidic connection between a first fluidic reservoir of ionic concentration solution and the nanopore, and includes a passage length having a fluidic passage width, along at least a portion of a fluidic passage length, that is greater than the diameter of the nanopore and less than the fluidic passage length. The fluidic passage has a fluidic passage fluidic resistance, R, of at least about 10% of the nanopore fluidic resistance, R, and no more than about 10 times the nanopore fluidic resistance, R. The nanopore is disposed in fluidic connection between the fluidic passage and a second fluidic reservoir of ionic concentration solution. At least one transistor is operatively connected electrically to sense electrical potential local to the fluidic passage.
