A Dual Sensor for pH and Hydrogen Peroxide Using Polymer-Coated Optical Fibre Tips

This paper demonstrates the first single optical fibre tip probe for concurrent detection of both hydrogen peroxide (H(2)O(2)) concentration and pH of a solution. The sensor is constructed by embedding two fluorophores: carboxyperoxyfluor-1 (CPF1) and seminaphtharhodafluor-2 (SNARF2) within a polyme...

description This paper demonstrates the first single optical fibre tip probe for concurrent detection of both hydrogen peroxide (H(2)O(2)) concentration and pH of a solution. The sensor is constructed by embedding two fluorophores: carboxyperoxyfluor-1 (CPF1) and seminaphtharhodafluor-2 (SNARF2) within a polymer matrix located on the tip of the optical fibre. The functionalised fibre probe reproducibly measures pH, and is able to accurately detect H(2)O(2) over a biologically relevant concentration range. This sensor offers potential for non-invasive detection of pH and H(2)O(2) in biological environments using a single optical fibre.
