Abstract

We report the successful fabrication and testing of an optical MEMS sensor for the detection of the toxic phenol, catechol. Catechol’s presence in food and drinking water posses a health concern due to its harmful effects on cell respiration. By-products of catechol oxidation have demonstrated increased absorbance changes in a chitosan film in the UV and near UV range. Our reported sensor takes advantage of this unique absorbance property to detect catechol by measuring the change in light intensity at 472 nm, thus eliminating non-specific responses that occur from other oxidized chemicals which do not cause the absorbance change. Concentrations as low as 1 mM catechol are detected while control experiments including ascorbic acid display no measurable response.
