Abstract: A method of fabricating a polarization sensor is described. It includes a quarter-wave plate to convert circularly polarized light into linearly polarized light. The quarter-wave plate is realized as a metasurface. The sensor also includes a linear polarizer to analyze the light generated by the quarter wave plate, and a photodetector to receive the analyzed light. The sensor may be combined with other linear polarization sensors to form a sensor capable of complete measurement of the polarization state of incident light.

Abstract: Provided herein are methods of detecting severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) in a sample. The methods include contacting the sample with a plurality of gold nanoparticles (AuNPs) and/or other plasmonic metal nanoparticles (MNPs) that are conjugated with at least two sets of antibodies, or antigen binding portions thereof, that binds to at least first and second epitopes of SARS-CoV-2 proteins, such as receptor-binding domain (RBDs) under conditions sufficient for the antibodies, or the antigen binding portions thereof, to bind to the first and second epitopes of the SARS-CoV-2 proteins in the sample to produce bound SARS-CoV-2 proteins. The methods also include detecting the SARS-CoV-2 proteins when aggregations of the bound SARS-CoV-2 proteins form with one another. Related compositions, reaction mixtures, devices, kits, and systems are also provided.
