Abstract
A sensor comprising a substrate (100) having a first surface (105) and a second surface (110) is described. The first surface has at least one sensor site (115) provided thereon. The substrate is configured such that on excitation of a sample provided at the sensor site, luminescence originating from the sensor site propagates into the substrate, the second surface of the substrate being configured to selectively transmit the luminescence propagating within the substrates at angles greater than the critical angle out of the substrate where it may be detected by a detector (160) provided below the substrate.
