Abstract
A novel optical chemical sensor for direct and continuous detection of organic species in process streams is described. The sensor is based on the use of surface plasmon resonance to amplify fluorescence emission from chemically selective membranes which can be deposited as Lang-muir-Blodgett films on thin metal island films.
