Abstract
Sequencing methods, devices, and systems are described. Arrays of nanoscale electronic elements comprising two electrodes separated by an insulating layer are used to provide sequence information about a template nucleic acid in a polymerase-template complex bound proximate to the insulating region. A sequencing reaction mixture comprising nucleotide analogs having impedance labels is introduced to the array of nanoscale electronic elements under conditions of polymerase mediated nucleic acid synthesis. The time sequence of incorporation of nucleotide analogs is determined by identifying the types of labels of the nucleotide analogs that are incorporated into the growing strand using measured impedance.
