Test card for assay and method of manufacturing same
First Claim
1. A method of manufacturing a test card for analysing a fluid sample, comprising:
- cutting at least a microchannel into a first polymer material to form a channel layer;
cutting a first aperture and a second aperture into a second polymer material to form a first substrate layer;
bonding the first substrate layer to a first side of the channel layer and a second substrate layer to a second side of the channel layer to form a single bonded layer with the microchannel passing therethrough and placing the first aperture and the second aperture in fluid communication with each other;
forming a third substrate layer to be thicker than the first substrate layer and the second substrate layer;
printing a conductive ink onto a first side of the bonded layer; and
adhering the third substrate layer to a second side of the bonded layer opposite the first side to form the test card, wherein the formed test card has a first surface formed by third substrate layer and an opposite second surface with the conductive ink exposed for contact with an outside source of current.

Abstract
A disposable test card configured to accept a fluid sample for an assay, and a method of manufacturing same, is disclosed herein. In a general example embodiment, a test card for analyzing a fluid sample includes a first substrate layer including an inlet port and an outlet port, a channel layer bonded to the first substrate layer, the channel layer including a microchannel placing the inlet port in fluid communication with the outlet port, and a second substrate layer bonded to the channel layer, the second substrate layer having electrodes printed adjacent to a target zone of the microchannel of the channel layer, wherein the electrodes are configured to raise the temperature of the fluid sample within the target zone of the microchannel when a current is applied thereto.
