Abstract

An improved method of analyzing target analytes in a sample is described. The method is based on creating an approximately homogeneous distribution of light in an anti-resonant guided optical waveguide to improve light-target interaction in a target-containing medium. The light-target interaction can be monitored by many different means to determine characteristics of the target analyte.
