Patent ID: 11067534

Abstract:
There is provided a multi-channel nanopore sensor having a plurality of independent nanopore sensors. Each independent nanopore sensor includes a nanopore disposed in a support structure. A fluidic connection is between a first fluidic reservoir, common to all of the independent nanopore sensors, and an inlet to the nanopore, with a first ionic solution of a first ionic concentration disposed in the first fluidic reservoir. A fluidic connection is between a second fluidic reservoir, common to all of the independent nanopore sensors, and an outlet from the nanopore, with a second ionic solution of a second ionic concentration, different than the first ionic concentration, disposed in the second fluidic reservoir. An electrical transduction element, disposed in contact with that ionic solution having a lower ionic concentration, is arranged at a site that produces an electrical signal indicative of electrical potential local to that ionic solution having a lower ionic concentration.
