Abstract: In a method for sensing translocation of a molecule through a nanopore, a molecule in a first fluidic solution in a first fluidic reservoir that is in direct fluidic connection with the nanopore is directed to a nanopore inlet and translocated through the nanopore to a nanopore outlet and through a fluidic passage that is in direct fluidic connection with the nanopore outlet, to a second fluidic solution in a second fluidic reservoir disposed in direct fluidic connection with the fluidic passage. The fluidic passage has at least one fluidic section in which a length of the fluidic section is greater than a width of the fluidic section. Translocation of the molecule through the nanopore is sensed by measuring the electrical potential local to the fluidic passage during the translocation of the molecule.

Abstract: To sense the translocation of a molecule through a nanopore, there is directed to an inlet of the nanopore, having a nanopore fluidic resistance, RP, a molecule disposed in a cis fluidic ionic solution having a cis fluidic access resistance, RC.

An indication of local electrical potential is produced at a site within the nanopore sensor that is on the trans fluidic ionic solution-side of the nanopore, to sense translocation of the molecule through the nanopore.
