A hydrogel modified electrode for application as a voltammetric temperature sensor and its use in oxygen detection

Abstract:

We report a hydrogel modified electrode based voltammetric "thermometer" and its application in amperometric oxygen detection so avoiding the need for external temperature monitoring to allow the rigorous measurement of oxygen concentrations. A platinum electrode was modified with a layer of agarose hydrogel containing decamethylferrocene (DmFc) and bisferrocene (BisFc) and a layer of pure ionic liquid containing no ferrocenes as solvent. The differences of the formal potentials between these...
