  • Patent number: 12631617
    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.

  • Patent number: 12509721
    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.

  • Publication number: 20250382602
    Abstract: The present invention relates to modified Dda helicases which can be used to control the movement of analytes such as polynucleotides. The modified Dda helicases are used in analyte detection and characterisation. The present invention also relates to novel protein pores and their uses in analyte detection and characterisation. The invention particularly relates to an isolated pore complex formed by a CsgG-like pore and a modified CsgF peptide, or a homologue or mutant thereof, thereby incorporating an additional channel constriction or reader head in the nanopore.
