An assay device for the quantitative determination of the concentration of at least one analyte in a liquid sample comprises a planar emitter 2, a planar detector 3, a lateral flow membrane 4 interposed between the emitter 2 and the detector 3, The lateral flow membrane 4 is formed from a light transmissive material and is capable of transporting fluid from the conjugate pad 5 to the wicking pad 7 by capillary action. The emitter 2 comprises an emission layer 9,16 of an organic electroluminescent material and the emission layer 9,16 is aligned with the test region 8,12 of the lateral flow membrane 4, whereby the emitter 2 is capable of illuminating the test region 8,12. The detector 3 comprises an absorption layer 10,15 of an organic photovoltaic material and the absorption layer 10,15 is aligned with the test region 8,12 of the lateral flow membrane 4, whereby the detector 3 is capable of detecting light from the test region 8,12. |
