Abstract

A first fluidic solution having a first ionic concentration is provided in a first fluidic reservoir in direct fluidic connection with a nanopore. A second fluidic solution, having a second ionic concentration, is provided in a second fluidic reservoir disposed in fluidic connection with the nanopore through a fluidic passage having at least one fluidic section in which the section length is greater than the section width. The electrical potential local to the fluidic passage is measured, and the resistance of both the fluidic passage the nanopore are determined based on the fluidic passage electrical potential. The fluidic passage resistance is compared with the nanopore resistance and at least one of the first and second ionic concentrations is adjusted based on the comparison. The measuring, determining, comparing, and adjusting steps are conducted until the fluidic passage resistance is between about 0.1 times and about 10 times the nanopore resistance.
