Nanopore sequencing mechanism：Nanopore sequencing

DNA / RNA sequencing technique

On the left is a drawing of the complex formed between alpha-hemolysin and dsDNA with linkage through an oligomer. On the right, movement of this complex in relation to a nanopore channel is shown sequentially in two steps (I) and (II). Once the complex is inserted into the nanopore, the alpha-hemolysin protein will be functional in the newly formed hybrid, biological and solid state, nanopore system.Illustration of how an electrical signal is generated from DNA passing through a nanopore channel.

Nanopore sequencing is a third generation[1] approach used in the sequencing of biopolymers — specifically, polynucleotides in the form of DNA or RNA.

Using nanopore sequencing, a single molecule of DNA or RNA can be sequenced without the need for PCR amplification or chemical labeling of the sample. Nanopore sequencing has the potential to offer relatively low-cost genotyping, high mobility for testing, and rapid processing of samples with the ...
