ABSTRACT:
A detection method is integrated with a filtering method and an enhancement method to create a fluorescence sensor (10) that can be miniaturized. The fluorescence sensor (10) comprises a thin film geometry including a waveguide layer (16), a metal film layer (20) and sensor layer (32). The thin film geometry of the fluorescence sensor allows the detection of fluorescent radiation over a narrow wavelength interval. This enables wavelength discrimination and eliminates the detection of unwanted light from unknown or spurious sources.
