Abstract:
1. A sensor for detecting an analyte, comprising: a substrate; recognition elements specific for the analyte, wherein the recognition elements are tethered to the substrate such that the recognition elements can be exposed to a sample; an excitation source for emitting a first light to excite a luminophore to emit a second light when the recognition elements interact with the analyte, wherein the first light has a first light peak intensity at a first wavelength, and wherein the second light has a second light band; a detector capable of detecting the second light emitted by the luminophore; a chamber located between the substrate and the excitation source and between the substrate and the detector, wherein when the analyte is introduced to the chamber it can contact the recognition elements; and an emission filter located between the detector and the chamber capable of filtering in a band gap that includes the first light peak intensity and excludes at least a portion of the second light band.
