Patent ID: 11454624

Abstract:
A test cartridge includes a membrane separating an internal space of the cartridge into a sample chamber and a second chamber. A first electrode is disposed within the sample chamber, and a second electrode is disposed within the second chamber. A device includes a dock and circuitry. The dock includes a first dock-terminal and a second dock-terminal, and is configured to receive the cartridge such that the circuitry is electrically connected to the electrodes via contact between terminals of the dock and terminals of the cartridge. The circuitry performs, while the cartridge remains docked with the dock: (a) a verification step that verifies an absence of nanopores in the membrane, (b) subsequently, a nanoporation subroutine, and (c) subsequently, an assay subroutine. The circuitry enables the nanoporation subroutine only if the verification step successfully verifies the absence of nanopores. Other embodiments are also described.
