Abstract
In this paper the results of detecting volatile organic compounds (VOC) employing surface plasmon-based sensors are presented. The initial step in preparing the sensing elements herein requires depositing Au° on a quartz slide. The sensing elements are based on either (1) freshly deposited Au° or (2) growth of a self assembled monolayer composite film (SAM) on to a freshly deposited Au° surface. The desired SAM is either (1) acid terminated using ω-mercaptoundecanoic acid (MUA-COOH) or (2) Cu2+ metal ion terminated yielding ω-mercaptoundecanoic acid-Cu2+ (MUA- Cu2+). The experimental apparatus shown here measures the reflectivity of the Au° surface as a function of time at a given angle. The response of this surface plasmon device to various VOC's is correlated to the composition of the SAM film.
