摘要: A sensor system for determining glucose concentration in a tear fluid sample includes 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. Alternatively, a vessel for receiving the tear fluid sample may include the enzyme portion on an inner wall thereof. A reference electrode is 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.
