Optical sensor-based cupric reducing antioxidant capacity (CUPRAC) assay

摘要

An example embodiment is an apparatus for measuring antioxidant presence comprising a solid media, and a reagent carried by the media, the reagent reactive with at least one antioxidant to cause changes in light that is incident upon the reagent while carried by the solid media.

主权项

1. An apparatus for measuring antioxidant capacity in a biological sample comprising:
a solid media, wherein the solid media is composed of paper or woven fabrics; and, a reagent carried by the media, wherein the reagent is comprised of copper and neocuproine (2,9-dimethyl-1,10-phenanthroline, abbreviated as Nc) chelator embedded in or adsorbed to the solid media and wherein the reagent is reactive with a number of antioxidants in a biological sample to cause changes in light that are incident upon the reagent while carried by the solid media, wherein the reagent has a standard reduction potential of about 0.6V.
