Patent number: 8821796Abstract: A mechanism is provided for sensing molecules. A twin-nanopore probe includes a first channel and a second channel. A first pressure-controlled reservoir is connected to the first channel to generate a positive pressure. A second pressure-controlled reservoir is connected to the second channel to generate a negative pressure. A container includes ionic solvent with molecules, and a tip of the twin-nanopore probe is submerged in the container of the ionic fluid with the molecules. The first channel, the second channel, the first pressure-controlled reservoir, and the second pressure-controlled reservoir are filled with the ionic fluid. The first pressure-controlled reservoir drives the ionic fluid out of the first channel and the second pressure-controlled reservoir draws in the ionic fluid with the molecules and solvent through the second channel. A flow of ionic current in the twin-nanopore probe is measured to differentiate the molecules that flow through the second channel.Type: GrantFiled: August 28, 2012Date of Patent: September 2, 2014Assignee: International Business Machines CorporationInventor: Hongbo Peng
