US 2019/0170904 A1 · PHOTONIC STUCTURE-BASED DEVICES AND COMPOSITIONS FOR USE IN LUMINESCENT IMAGING OF MULTIPLE SITES WITHIN A PIXEL, AND METHODS OF USING THE SAME

Abstract

A device for luminescent imaging includes an array of imaging pixels, a photonic structure over the array of imaging pixels, and an array of features over the photonic structure. A first feature of the array of features is over a first pixel of the array of imaging pixels, and a second feature of the array of features is over the first pixel and spatially displaced from the first feature. A first luminophore is within or over the first feature, and a second luminophore is within or over the second feature. The device includes a radiation source to generate first photons having a first characteristic at a first time, and generate second photons having a second characteristic at a second time. The first pixel selectively receives luminescence emitted by the first and second luminophores responsive to the first photons at the first time and second photons at the second time, respectively.
