Researchers from the University of Manchester and Aix-Marseille University developed a new optical device that can analyze a single molecule quickly, using Plasmonics (the study of vibrations of electrons in different materials). This could lead to virus detectors, fast and accurate athlete drug testing and explosive tracking in airports.

The device uses artificial materials with topological darkness that are highly sensitive to a single small molecule (this relies on topological properties of light phase). The artificial material is covered with graphene (which they say is one of the best materials that can be used to measure the sensitivity of molecules). Basically the device is like a single-molecule microscope.
