Anodic deposition of DEB onto CFMs displayed a characteristic peak for generation of the ethynyl radical, as seen in Figure . This characteristic peak appeared at a different potential for different electrodes, as seen in Figure , but generally appeared in the potential range of 1.5-1.7 V. This is comparable to observations previously reported by Geiger and colleagues for glassy carbon electrodes . Geiger and colleagues previously reported successful deposition of multiple monolayers when they applied multiple scans of the deposition waveform . In this paper, we refer to each application of an entire waveform for deposition as a 'scan.' Thus, when we applied the waveform thrice we refer to it as three scans. Geiger and colleagues observed the polymerization of ethynyl terminal molecules during multi-scan depositions, characterized by an increase in current at the potential at which ethynyl radical formation is observed . In contrast, as seen in Figure , we observed a decrease in the current at the ethynyl radical potential for subsequent scans, suggesting the absence of polymerization. This was advantageous as we did not want the DEB to self-polymerize before attaching to the electrode. Instead, our data suggests that the DEB formed covalent bonds to the carbon surface. With each scan, there were less surface area on the CFM for the DEB to attach, thereby reducing ethynyl radical formation and resulting current.
