Abstract

A multi-analyte sensor has been prepared that allows O₂, CO₂ and pH to be monitored simultaneously with rapid response to all three analytes. The sensor is fabricated to photodepositing analyte-sensitive polymer matrices on the distal surface of an imaging fiber. The array shows sensitivity to pH in the range 5.0 - 8.0, CO₂ from 0 - 15% and O₂ from 0 - 100%.
