Abstract

The present invention provides a non-electrical, non-mechanical, and non-software oriented methodology for protecting sensors, with specific applicability to retarding or eliminating optrode biofouling. FIG. 1 illustrates Halobenzonitriles, or which, chlorothalonil, the preferred biocide for the protection of optrodes, is effective even a ppb concentrations.
