Patent number: 10816466Abstract: An analysing apparatus comprises a fluid container defining a sample chamber. A sensor having a transparent body with a nanostructured surface is coupled to the fluid container such that the nanostructured surface is exposed to the sample chamber. An excitation and detection apparatus directs a beam of incident polarised electromagnetic radiation onto the reverse face of the body at the Brewster angle, causing no or substantially no reflection of the polarised radiation from the reverse face. The beam of reflected radiation emerges from the reverse face after reflection from the nanostructured surface. The apparatus is simpler and cheaper in comparison with known alternatives that use ATR prisms to create ATR of the light to excite a planar surface.Type: GrantFiled: October 4, 2016Date of Patent: October 27, 2020Assignee: Causeway Sensors LimitedInventors: Robert Pollard, Anthony Murphy, Breandan Hill
