An improved protamine-sensitive electrode based on a polymeric membrane doped with the charged ion exchanger dinonylnaphthalenesulfonate (DNNS) is used for monitoring heparin concentrations in whole blood. The electrode exhibits significant nonequilibrium potentiometric response to polycationic protamine over the concentration range of 0.5-20 mg/L in undiluted whole-blood samples. The sensor ca...

In this work, we are presenting an iron ion (Fe 3+ ) potentiometric sensor based on functionalized ZnO nanorods with selective ionophore (18 crown 6). Zinc oxide nanorods with a diameter of about 100 to 150 nm and 1μm in length were grown on gold coated glass. The selective Fe 3+ ionophore sensor with highly aligned ZnO nanorods has given high sensitivity, acceptable selectivity, reproducibilit...
