✦ Synopsis

Evanescent field optical fibre sensors have been widely exploited in biochemical assays. The use of multimode fibres has revealed a number of limitations, especially in the case of absorption sensors. In this paper, we describe the use of a tapered single mode optical fibre as an optimised system to act as an evanescent wave absorption sensor, with a calcium detection scheme as a model system.

An artificial neural network (ANN) has been applied for the analysis of the response of an optical fibre pH sensor. The optrode was based on a 3,4,5,6-tetrabromophenol sulphonephthalein indicator, which was covalently bound onto aminopropyl glass beads, then packed at the tip of a bifurcated fibre-o
