Patent ID: 7947485

Claim:
A molecular analysis device, comprising: a first reservoir: a second reservoir; a nanochannel configured to carry at least one molecule having one or more nucleotide bases from the first reservoir to the second reservoir, the nanochannel having a cross section less than about 100 nanometers; and a molecule sensor located near the nanochannel, the molecule sensor comprising; a single electron transistor comprising: a first terminal; a second terminal; a third terminal configured for biasing an electronic effect of the single electron transistor; and at least one quantum dot fixed between the first terminal and the second terminal; and a nitrogenous material disposed on the at least one quantum dot and configured to form a transitory bond with the at least one molecule as the at least one molecule passes through the nanochannel from the first reservoir to the second reservoir; wherein the molecule sensor develops the electronic effect responsive to the transitory bond.
