Functionalized surfaces for the destruction of pathogens and organics

DWPI Title: Capturing contaminant by exposing fluid stream comprising concentration of contaminant to high charge density binding component (attached to surface of substrate) to reduce concentration of contaminant in fluid stream
Abstract: The disclosure is directed to a surface having a binding component applied thereto for the adsorption or capture of pathogens and organic molecules or materials. The surface may be a component of a porous or nonporous substrate. The binding component may also bind a photocatalyst to the surface for photocatalytic destruction of the captured pathogens and organic molecules or materials.
Use: The method is useful for capturing a contaminant (claimed).
Advantage: The method is less expensive and more effective than current methods; effectively removes pathogens and/or organic material from municipal water; incorporates in a membrane, a coating for preventing or removing biofouling of the membrane and extending its useful lifetime; provides alternatives to titanium dioxide as photocatalytic materials for coating surfaces; and provides a layering method of affixing photocatalytic agents to surfaces, using materials that are resistant to photocatalytic oxidation.
Novelty: A contaminant is captured by exposing a fluid stream comprising a concentration of a contaminant to a high charge density binding component to reduce the concentration of the contaminant in the fluid stream. The high charge density binding component is attached to a surface of a substrate.
