Abstract: Aspects of the present disclosure are directed toward detection of leakage from an enclosed component using an apparatus. The apparatus includes a printed circuit board (PCB) including a first conductive trace, a second conductive trace, and sets of terminals electrically connected to the first and second conductive traces configured and arranged to indicate changes in impedance caused by leaked liquid. The respective portions of the first and second conductive traces are interleaved, and configured and arranged to suspend flow of the leaked liquid from an enclosed component, thereby causing a change in impedance between at least one of the sets of terminals.

Abstract: The present invention is directed to systems, devices and methods for identifying biopolymers, such as strands of DNA, as they pass through a constriction such as a carbon nanotube nanopore. More particularly, the invention is directed to such systems, devices and methods in which a newly translocated portion of the iopolymer forms a temporary electrical circuit between the nanotube nanopore and a second electrode, which may also be a nanotube. Further, the invention is directed to such systems, devices and methods in which the constriction is provided with a transnaionilized unit which, together with a newly translocated portion of the biopolymer, forms a temporary electrical circuit that can be used to characterize the portion of the biopolymer.

Abstract: A device for reading the sequence of a polymer, consisting of a first electrode and a second electrode, each electrode being functionalized with a reader molecule strongly bonded to the electrodes, but forming weak bonds with a molecule to be sequenced. In particular, the reader molecule is designed to form bonds with at least two points on the target molecule such that the target molecule is trapped between a first reader molecule on one electrode and a second reader molecule on the second electrode, with the overall size of the molecular complex being small enough to permit significant electric current to flow.

Abstract: The present invention provides a device for analyzing the composition of a heteropolymer comprising a carbon nanotube through which the heteropolymer is driven by electrophoresis. The carbon nanotube also serves as one electrode in a reading circuit. One end of the carbon nanotube is held in close proximity to a second electrode, and each end of the carbon nanotube is functionalized with flexibly-tethered chemical-recognition moieties, such that one will bind one site on the emerging polymer, and the second will bind another site in close proximity, generating an electrical signal between the two electrodes when the circuit is completed by the process of chemical recognition.
