Abstract: A process of manufacturing a microfluidic device (200, 201, 202, 300, 301, 302, 400, 401, 402) includes the steps of attaching a monolayer of polymer beads onto a first substrate (210, 410) depositing a metal oxide film onto the first substrate (210, 410) over the monolayer of polymer beads, and removing the polymer beads to form an array of metal oxide nano-wells (240, 440) wherein the first substrate (210, 410) is exposed at the bottom of the nano-wells (240, 440). The process also includes depositing an organophosphate layer onto the metal oxide film. The process also calls for depositing a silane coating layer or an acrylate polymer onto the exposed first substrate (210, 410). The method further includes bonding a second substrate (220, 420) to the first substrate (210, 410) to enclose the array of metal oxide nano-wells (240, 440) in a cavity within the first and second substrates (210, 220, 410, 420).

Abstract: A method of making a microfluidic device (200, 201, 300) can include depositing a layer of photoresist onto a first substrate (210, 270, 310), selectively removing the photoresist to expose portions of the first substrate (210, 270, 310), etching the exposed portions of the first substrate (210, 270, 310) to form an array of nano-wells (240, 340), coating each nano-well (240, 340) with metal oxide, and coating the metal oxide on each nano-well (240, 340) with a first material to increase binding of DNA, proteins, and polynucleotides to the metal oxide. A layer of a second material can be deposited on interstitial areas between the nano-wells (240, 340) to inhibit binding of DNA, proteins, and polynucleotides to the interstitial areas. A second substrate (220, 320) can be bonded to the first substrate (210, 270, 310) to enclose the array of nano-wells (240, 340) in a cavity.
