We provide and discuss electrochemical quartz crystal microbalance (EQCM) measurements confirming previously-reported observations that poly-L-lysine films deposited from solution under anodic conditions grow at a constant deposition rate for extended periods of time. Compared to our previous results using Pt, we find that indium tin oxide (ITO) offers an effective surface for film growth where water oxidation is sufficiently suppressed to allow uniform films to be deposited. The fact that the previous results on ITO have been reproduced is positive for the study of polyelectrolyte film creation, and has implications for the use of these films to increase the biocompatibility of hard conducting materials used as electrodes.
