Research Sensors are ubiquitous in today’s society, from temperature sensors like thermometers to acoustic sensors such as microphones. But there are few stable sensors available to monitor chemical changes in our environment. My research interests combine photo-switchable dyes with molecularly imprinted polymers in an effort to create photo-activated sensors that are reusable and have enhanced chemical stability. The primary focus is the synthesis of spiropyran containing polymers, and the development of methodology for quantitative analysis of the polymer substrates using diffuse reflectance UV-Visible spectroscopy. The spiropyran molecules change color in response to light and complexation with metal ions. Ultimately, the development of these types of stable chemical sensors would enable long-tern in-situ studies of metal concentrations in polluted waters.
