Abstract
A method is provided for detecting an analyte in a liquid sample, the method using light energy propagational properties of an analyte-responsive polymer. The analyte-responsive polymer is interfaced with a means to detect changes in the light propagation of the analyte-responsive polymer and the changes are correlated to the amount of analyte in the liquid sample.
