Abstract

Official abstract text for this publication.

A technique relates to an integrated nanofluidic device. A loading layer includes an inlet channel reservoir, a diverted fraction reservoir, and a passed fraction reservoir. A sorting layer is attached to the loading layer such that fluid is permitted to communicate between the loading and sorting layers, where the sorting layer includes a bank of sorting elements. The sorting layer has inlet channels and outlet channels connected to the sorting elements, and the inlet channel reservoir is connected to the inlet channels by an inlet feed hole. The diverted fraction reservoir is connected to the outlet channels by a diverted fraction outlet feed hole, and the passed fraction reservoir is connected to the sorting elements by passed fraction feed holes. The passed fraction feed holes are respectively connected to the sorting elements.

First claim

Opening claim text (preview).

What is claimed is: 1. A method of configuring an integrated nanofluidic device, the method comprising: providing a loading layer, as a single layer, including an inlet channel reservoir, a diverted fraction reservoir, and a passed fraction reservoir; and attaching a sorting layer, as another single layer, to the loading layer such that fluid is permitted to directly communicate between the loading and sorting layers, the sorting layer including a bank of sorting elements, wherein the sorting layer has inlet channels and outlet channels connected to the sorting elements, wherein the inlet channel reservoir is connected to the inlet channels by an inlet feed hole, wherein the diverted fraction reservoir is connected to the outlet channels by a diverted fraction outlet feed hole, and wherein the passed fraction reservoir is connected to the sorting elements by passed fraction feed holes, the passed fraction feed holes respectively connected to the sorting elements, wherein the loading layer and the sorting layer are directly attached to one another thereby forming two layers, wherein the inlet feed hole and the diverted fraction outlet feed hole are both in the sorting layer. 2. A method of configuring an integrated nanofluidic device, the method comprising: providing a loading layer, as a single layer, including an inlet channel reservoir, an inlet vias reservoir, a diverted fraction reservoir, and a passed fraction reservoir; and arranging a sorting layer, as another single layer, attached to the loading layer such that fluid is permitted to directly communicate between the loading and sorting layers, the sorting layer including a bank of sorting elements, wherein the sorting layer has inlet channels and outlet channels connected to the sorting elements, wherein the inlet channel reservoir is connected to the inlet channels by an inlet feed hole, wherein the diverted fraction reservoir is connected to the outlet channels by a diverted fraction outlet feed hole, wherein the passed fraction reservoir is connected to the sorting elements by passed fraction feed holes, the passed fraction feed holes respectively connected to the sorting elements, and wherein the inlet vias reservoir is connected to the sorting elements by inlet via holes, wherein the loading layer and the sorting layer are directly attached to one another thereby forming two layers, wherein the inlet feed hole and the diverted fraction outlet feed hole are both in the sorting layer. 3. The method of claim 2 , wherein the sorting elements each include a nanopillar array configured to sort particles.
