ABSTRACT:
An improved method of analyzing target analytes in a sample is described. The method is based on anti-resonant guided optical waveguides which enables a strongly improved light-target interaction since the light can be guided within the target-containing medium. The light-target interaction can be monitored by many different means to determine characteristics of the target analyte. The anti-resonant waveguide concept is suitable for a large variety of characterization methods and combinations of them, since it is relatively unaffected by changes to both wavelength and film thickness.
