N2 - Nanocomposite films comprised of CdSe quantum dots embedded in polymer matrices were studied for their potential development and use as highly sensitive and selective hydrocarbon sensing materials. In previous studies we have reported a factor of 5-7 enhancement in the sensitivity to xylenes, along with a 2-3 times enhancement in the selective detection of xylenes over toluene. This increased sensitivity and selectivity for the detection of aromatic hydrocarbons, which only differ by a single methyl group, is a promising result for the development of a portable petroleum by-products chemical sensor. The next phase of these studies is to move from sequential to parallel measurements, therefore studies have been initiated for the development of QD based arrays as the hydrocarbon sensing elements. The sensing arrays allow us to make measurements of up to six films simultaneously, which will potentially increase the hydrocarbon detection selectivity of our current experiments.
