1. A sensor for determining glucose concentration in a tear fluid sample, comprising:

  • a working electrode including an immobilized glucose oxidase enzyme portion for reacting with glucose in the tear fluid sample, and a selectivity portion for enhancing the selectivity for glucose over electroactive interferent species in the tear fluid sample; and

    a reference electrode disposed adjacent the working electrode;

    wherein the electrochemical reaction of the enzyme portion with glucose in the tear fluid sample generates a current related to the glucose concentration in the tear fluid sample.
