Patent ID: 8702940

Claim:
A method for capturing molecules, the method comprising: providing a nanopore through a membrane separating a first chamber from a second chamber, the nanopore, the first chamber, and the second chamber being filled with ionic buffer; wherein meeting tips of a left triangle and a right triangle unite to form the first chamber; aligning an entrance of the nanopore under the meeting tips of the left triangle and the right triangle that form the first chamber; wherein the nanopore is formed perpendicular to the meeting tips of the left triangle and the right triangle that form the first chamber; configuring a high current density at the meeting tips in order for the meeting tips to comprise a high intensity electric field compared to other areas of the first chamber comprising low intensity electric fields; wherein when a first voltage is applied between the left triangle and the right triangle, a narrowness of the meeting tips concentrates the molecules at the meeting tips above the entrance of the nanopore because the narrowness of the meeting tips causes the high current density; and resulting from the high current density, configuring the meeting tips to comprise the high intensity electric field which concentrates the molecules at the entrance of the nanopore; wherein a second voltage applied between the first chamber and the second chamber drives the molecules, concentrated at the entrance of the nanopore, through the nanopore.
