The anti-bacterial effect of an electrochemical anti-fouling method intended for the protection of miniaturised oceanographic sensors.

An electrochemical anti-fouling method, based upon the generation of chlorine from seawater, was applied to a proprietary design of Lab on a Chip conductivity, temperature and dissolved oxygen sensor. The method was evaluated using PCR after a six-week field trial in which it significantly reduced the burden of bacterial biofouling.
