Paper Abstract

This paper describes a simple, low cost technique for producing a micro-oxygen sensor based on indicator chemistry, and results obtained using this device to monitor dissolved oxygen concentration are reported. The technology is based on the use of submicron optical fiber tips which have a fluorescent chemical reagent immobilized on their tip surface. Fiber tips were formed by drawing single-mode optical fiber in a fusion splicer. Sol-gel films doped with a fluorescent, oxygen sensitive chemical indicator were then deposited on the surface of the fiber tip using dip-coating techniques. The sensors that we have developed using these coating technologies are reversible and have response times of a few tenths of a second.
