Zusammenfassung:Devices, systems, and methods for detection of an analyte in a sample are disclosed. In some embodiments, an optical sensor (100) can include a light source (110), a detector (120), a metallic layer (104) and a plurality of dielectric pillars (106) extending through the metallic layer. The metallic layer (104) and the plurality of dielectric pillars (106) are designed such that a plurality of regions of concentrated light (107) can be supported in proximity to the ends of the plurality of dielectric pillars (106) at one side of the metallic layer thereof when an opposite surface of the metallic layer is illuminated by the light source. Concentrated light within one or more of these regions can interact with an analyte molecule (112) and can be detected by the detector (120) positioned on the same side as these regions, allowing for detection of the analyte .
