Patent ID: 8821796

Claim:
A system for sensing molecules, the system comprising: a twin-nanopore probe comprising a first channel and a second channel; a first pressure-controlled reservoir connected to the first channel, the first pressure-controlled reservoir configured to generate a positive pressure; a second pressure-controlled reservoir connected to the second channel, the second pressure-controlled reservoir configured to generate a negative pressure; a container comprising ionic solvent with the molecules, a tip of the twin-nanopore probe being submerged in the container of the ionic fluid with the molecules; wherein the first channel, the second channel, the first pressure-controlled reservoir, and the second pressure-controlled reservoir are filed with the ionic fluid; the first-controlled reservoir configured to drive the ionic fluid out of the first channel and the second pressure-controlled reservoir configured to draw in the ionic fluid mixed with the molecules and the solvent through the second channel; and the twin-nanopore probe configured to facilitate a flow of ionic current that is measured to differentiate the molecules that flow through the second channel.
