Abstract:
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.

Claim (Index 38):
A method of analysing a sample using a sensor comprising a transparent body with a reverse face and an obverse face, the obverse face having a nanostructured surface, the nanostructured surface comprising a plurality of elongate nanostructures having a respective longitudinal axis that is disposed substantially perpendicularly to the obverse face, the method comprising:\n exposing the nanostructured surface to the sample; directing a beam of incident polarised electromagnetic radiation onto the reverse face of the body at an angle that causes no or substantially no reflection of the polarised radiation from the reverse face; and directing to a detector a beam of reflected radiation, said beam of reflected radiation comprising said incident radiation that emerges from the reverse face after reflection from said nanostructured surface.
