Fecha de publicación: -- Fuente: WIPO "tomato" Disclosed herein is a device for chiral sensing comprising a chiral plasmonic substrate, wherein when the device is assembled together with a first light source, a liquid sample comprising a plurality of chiral analytes, a second light source, and an instrument, the first light source is configured to illuminate the chiral plasmonic substrate with electromagnetic radiation; and the second light source is configured to illuminate the chiral plasmonic substrate with circularly polarized electromagnetic radiation. The instrument is configured to process electromagnetic signal from the first light source and the second light source to determine a property of the liquid sample.
