An electroanalytical concept of biamperometry for such sensing systems has been overlooked due to widespread potentiostat-controlled experiments. Herein, biamperometry is introduced as a powerful tool. In particular, its ability to eliminate electrochemical interference is highlighted for a case study on employing [Fe(CN)(6)](4-)/[Fe(CN)(6)](3-), aminoferrocene (Fe2+)/[Ru(NH3)(6)](3+), and ascorbic acid as two redox pairs and one interfering compound, respectively. A specific signal 15 times higher than that of an unspecific signal is observed, even under unfavorable conditions such as a 1:5 molar ratio of specific-to-interfering redox entities. This system is successfully used to determine glucose in blood plasma. A further promising usage of biamperometry is illustrated by the study of an unstable redox system: the oxygen-dependent oxidation of [Ru(NH3)(6)](2+) in an aqueous environment. ER -
