A membrane-spanning nanopore is provided, the nanopore comprising: a. one or more polynucleotide strands that provide a scaffold component; and b. a plurality of polynucleotide strands that provide a plurality of staple components; wherein each of the plurality of staple components hybridise to the scaffold component; wherein the orientation of a major portion of at least one polynucleotide strand comprised within the scaffold component is substantially parallel to a planar surface of a membrane as well as embedded within and substantially coplanar with the membrane; wherein the nanopore defines a channel that is suitable for perforating the membrane; the channel having a longitudinal axis extending along the centre thereof and a minimum internal dimension perpendicular to the longitudinal axis of at least about 3 nm. A membrane comprising the nanopore, biological sensors comprising the membrane and a method for molecular sensing using the membrane are also disclosed.

Membrane bound nucleic acid nanopores

The invention relates to mutant forms of CsgG. The invention also related to analyte detection and characterisation using CsgG.

Mutant CsgG pores

A membrane-spanning nanopore is provided that comprises: i. at least one scaffold polynucleotide strand; ii. a plurality of staple polynucleotide strands; and iii. at least one hydrophobically-modified polynucleotide strand, wherein the at least one hydrophobically-modified polynucleotide strand comprises a polynucleotide strand and a hydrophobic moiety; wherein each of the plurality of staple polynucleotide strands hybridises to the at least one scaffold polynucleotide strand to form the three-dimensional structure of the membrane-spanning nanopore, and wherein the at least one hydrophobically-modified polynucleotide strand hybridises to a portion of the at least one scaffold polynucleotide strand, the membrane-spanning nanopore defining a central channel with a minimum internal width of at least about 5 nm. Membranes comprising the membrane-spanning nanopore and applications of those membranes are also provided.

Membrane-spanning nanopores

Mutant pores

The invention relates to mutant forms of the outer membrane-located lipoprotein CsgG, in particular, modifications at one or more of positions Tyr51; Asn55; and Phe56. The invention also relates to analyte detection and characterisation using said mutant CsgG.
