Colorimetric sensors

Our laboratory has been working for several years on development of colorimetric and fluorescent sensors based upon polydiacetylene (PDA) – a unique conjugated polymer. We have demonstrated applications of varied PDA-based sensor configurations, including vesicles, solid-supported films, PDA/sol-gel constructs, and PDA-labeled live cells, and investigated their use in chemical- and biological sensing applications.
