Abstract
The detection of a chemical specie of interest is accomplished by immobilizing sensing molecules on the inner wall of a liquid core optical waveguide, the waveguide comprising a capillary tube and the sensing molecules being selected to interact with the specie of interest carried by the liquid which forms the waveguide core. The interaction produces a change in an optical characteristic of the waveguide which may be detected by illuminating the waveguide with analysis light.
