Abstract:
1. A filter, comprising: at least one layered structure interior to an outermost bounding surface of the filter; wherein each layered structure comprises a carbon structure, a coating totally external to and having an outermost bounding surface in direct mechanical contact with an innermost bounding surface of the carbon structure, and a heparin layer having an outermost bounding surface in direct mechanical contact with an innermost bounding surface of the coating; wherein the carbon structure comprises carbon; wherein the coating comprises a coating material consisting of cellulose or a methacrylate selected from the group consisting of polymethylmethacrylate (PMMA), polyethylmethacrylate (PEMA), and polyhydroxyethylmethacrylate (PHEMA); wherein the heparin layer comprises heparin; wherein the layered structure is configured to remove a contaminant in a flowing liquid as the flowing liquid flows through the filter by flowing through a flow area of the filter; wherein the carbon structure surrounds the entire coating; wherein the coating is totally external to, disposed between, and in direct mechanical contact with, the heparin layer and the carbon structure; wherein an innermost bounding surface of the heparin layer coincides with an outermost bounding surface of the flow area; and wherein the heparin layer is totally external to, disposed between, and in direct mechanical contact with, the flow area and the coating.
