Abstract: Luminescent imaging films (100) for fluorescent enhancement and methods of making and using the same are provided. The films (100) include a flexible carrier layer (1109, and a pattern of photonic structure (120) disposed on the flexible carrier layer, which is interspersed with an anti-biofouling material (130) to provide a pattern of analyte sites (132). The pattern of photonic structure includes a patterned high-refractive-index dielectric material surface (123) so as to provide resonance at the excitation or emission wavelength to enhance a fluorescence signal from labeled analytes.

Abstract: An optical stack for sensing a presence of an analyte is provided. The optical stack includes a sensor material. The sensor material includes a first optical response including a first optical property having a second value in response to an excitation signal including the first optical property having a first value different from the second value. The first optical response includes a second optical property sensitive to the presence of the analyte. The optical stack includes a first optical film disposed proximate the sensor material and includes a third optical property having respective third and fourth values in response to the respective first and second values of the first optical property. The third value is different from the fourth value by at least a factor of 2.
