Abstract :
Instrumentation for optrode development in an intrinsic configuration was demonstrated by fluorescence from pyrene-labeled concanavalin A absorbed to the surface of an optical fiber. A system showing sensitivity, high selectivity, and reversibility was derived from the fluorescence detection of acetylcholine receptor binding to agonist. Fluorescence enhancement was seen for systems where a fluorophore was nonspecifically labeled to the receptor/membrane structure and also where only the lipid was fluorescent.<>
