Abstract: A biochemical sensing system senses interactions between molecular entities and nanopores using a sensor device comprising an array of sensor elements that support the nanopores. A switch arrangement selectively connects detection channels for amplifying sensed electrical signals to respective sensor elements. On the basis of an analysis of the amplified electrical signal output from the detection channels, detection of completion of interactions at sensor elements occurs. In response thereto, the switch arrangement is controlled to connect the detection channel connected to a sensor element at which completion of an interaction has been detected to a further sensor element.

Abstract: Methods of characterizing an analyte using a nanopore. One aspect features methods for characterizing a double-stranded polynucleotide using a nanopore, e.g., without using a hairpin connecting a template and a complement of the double-stranded polynucleotide. Another aspect features methods for characterizing an analyte using a tag-modified nanopore with increased sensitivity and/or higher throughput. Compositions and systems including, e.g., adaptors for attachment to double-stranded polynucleotides and tag-modified nanopores, which can be used in the methods are also provided.
