Description	Catalytic properties of rhodium and some of its salts, namely, RhO2, Rh2O3 and chlorobis(2-phenylpyridine)rhodium(III) dimer (CFPRD) were tested as mediators/catalysts of electron transfer in electrochemical biosensors for the determination of glucose. Measurements were realized using flow injection system and screen-printed carbon electrodes containing glucose oxidase as a model redox enzyme. Sensors with RhO2 was found the best exhibiting a linear increase of the amperometric signal for glucose concentrations in the range of 5.5x10-5 - 1.4x10-3 M with a detection limit of 2.2x10-5 M under optimized flow rate of 0.2 mL min-1 in 0.1 M phosphate buffer (pH 7.5) carrier. A metal rhodium-based sensor exhibited a linear increase in the range of 2.8x10-4 - 1.4x10-3 M, a sensor modified with Rh2O3 showed similar linear dependence in the range of 1.4x10-3 - 5.5x10-3 M. Concerning sensors modified with CFPRD, a linear concentration dependence was observed in the range of 5.5x10-3 - 2.8x10-2 M.
