Patent Images
1. A bilirubin sensor comprising:
- a working electrode with a first chemical matrix disposed thereon, the first chemical matrix containing a binder wherein the first chemical matrix is capable of oxidizing all oxidizable species in a fluid sample;
a substrate electrode with a second chemical matrix disposed thereon, the second chemical matrix containing a binder and a chemical agent that consumes bilirubin wherein the second chemical matrix is capable of oxidixing all oxidizable species in the fluid sample except bilirubin;
a reference electrode; and
a sample chamber containing the working electrode, the substrate electrode and the reference electrode.
