Real time electronic sequencing devices, chips, and systems are described. Arrays of nanoFET devices are used to provide sequence information about a template nucleic acid in a polymerase-template complex bound to the nanoFET. The nanoFET devices typically have a source, a drain and a gate comprising a nanowire. A single polymerase enzyme complex comprising a polymerase enzyme complexed with the template nucleic acid is bound to the gate. The polymerase is bound to the gate non-covalently through a polymeric binding agent that has two strands, each strand interacting with the nanowire such that the polymerase is in a central location between the strands with the polymeric binding agent extending away from the polymerase complex along the nanowire in both directions. |
