Comparison of unusual carbon-based working electrodes for electrochemiluminescence sensors

- Novel carbon based materials have been used as a working electrode for electrochemiluminescence detection.
- Biomass material was found to be an attractive working electrode material due to its porous structure.
- An efficient, stable, cost effective and green alternate to traditionally used glassy carbon electrode for biosensor.

In this work, unconventional carbon-based materials were investigated for use in electrochemiluminescence (ECL) working electrodes. Precursors such as bamboo, pistachio shells, kevlar® fibers and camphor were differently treated and used as working electrodes in ECL experiments. After a proper process they were assembled as electrodes and tested in an electrochemical cell. Comparison among them and with a commercial glassy carbon electrode (GCE) shows a very good response for all of them thus demonstrating their potential use as disposable low-cost electrodes for early detection electrochemical analysis.
