    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.

    摘要: A rotating electrode configuration lowers the detection limits of polyion-sensitive membrane electrodes. Planar potentiometric polycation and polyanion-sensitive membrane electrodes were prepared by incorporating tridodecylmethylammonium chloride and calcium dinonylnaphthalene sulfonate, respectively, into plasticized PVC or polyurethane membranes, and mounting discs of such films on an electrode body housed in a rotating disk electrode apparatus of the type used in voltammetry. Due to the unique non-equilibrium response mechanism of such sensors, rotation of the polyion-sensitive membrane electrodes at 5000 rpm resulted in an enhancement in the detection limits toward heparin (polyanion) and protamine (polycation) of at least 1 order of magnitude (to 0.01 U/ml for heparin; 0.02 μg/ml for protamine) over that observed when the EMF responses of the same electrodes were assessed using a stir-bar to achieve convective mass transport.
