Carbon-based materials for ECL detection

The present work reports on the use of different carbon-based electrodes for ElectroChemiLuminescence (ECL) detection. Carbon NanoTubes (CNT), Glassy Carbon (GC) and Silicon Carbide (SiC) were studied and their ECL performance measured. CNT electrodes allow for the detection of lower Ruthenium concentrations compared with the GC ones, but they present a minor reproducibility. Preliminary analysis of SiC electrodes shows that it is a promising material to be used in ECL, especially for biological application due to its biocompatibility.
