Abstract
A device for detecting a compound in a sample includes a substrate and a self-assembled monolayer. The substrate includes a support with a metallized top surface, and the self-assembled monolayer includes an alkanethiol attached to the metallized top surface of the substrate and having a functional group that reversibly or irreversibly interacts with the compound. A liquid crystal is disposed on the self-assembled monolayer opposite the side of the self-assembled monolayer attached to the metallized top surface of the substrate. The liquid crystal includes a moiety that interacts with the functional group of the alkanethiol. When the compound is present in a sample that that contacts the self-assembled monolayer, the orientation of the liquid crystal is altered.
