Abstract: A device, or a pixel of a device, for filtering of incident radiation includes an array of discrete micro-resonant elements in an encapsulated layer, the encapsulating material having a lower index of refraction than the micro-resonant elements. A highly reflective filtering structure is positioned a first distance above the encapsulated layer and/or a second distance below the encapsulated layer, and is characterized by a stopband. The array of discrete micro-resonant elements is configured to transmit a passband of incident radiation centered around a center wavelength that falls within the stopband of the highly reflective filtering structure, and to minimize a dependence of the center wavelength on an angle of incidence (AoI) of the incident radiation. A pixelated device includes a plurality of pixels, each having an array of the discrete micro-resonant elements tuned to transmit a different passband having a different center wavelength, while minimizing dependence on AoI.

Abstract: A surface plasmon resonance (SPR) sensor is provided that has enhanced sensitivity. The sensor's plasmonic chip has intrinsically disordered proteins (IDPs) that undergo enzyme-free folding upon binding to an analyte. This binding results in a detectable change in refractive index and thereby permits detection of the analyte.
