Detecting SNPs using a synthetic nanopore.

Abstract excerpt

We have discovered a voltage threshold for permeation through a synthetic nanopore of dsDNA bound to a restriction enzyme that depends on the sequence. Molecular dynamic simulations reveal that the threshold is associated with a nanonewton force required to rupture the DNA-protein complex. A single mutation in the recognition site for the restriction enzyme, i.e., a single nucleotide polymorphism (SNP), can...
