ABSTRACT:
The present invention proposes a sub-wavelength luminescence sensor, such as e.g. a luminescence biosensor or a luminescence chemical sensor, comprising at least two wire grids (1, 2) positioned perpendicular with respect to each other. The luminescence sensor, in which the excitation radiation is efficiently used and the luminescence radiation is efficiently detected, has an improved signal-to-noise ratio and a separated excitation and luminescence radiation.
