Popis:	The authors have prepared a pH fiber optic sensor based on fluorescence intensity. Fluoresceinamine is incorporated into an acrylamide-methylenebis(acrylamide) copolymer that is attached covalently to a surface-modified glass fiber via thermal or photopolymerization. The sensor gives instantaneous responses and reversible measurements over the pH range of 4.0-8.0 with signal-to-noise ratios of typically 275/1. The results indicate that specific fiber optic chemical sensors can be miniaturized and still retain sufficient signal intensity and stability.
