The invention relates to the amplification of the fluorescence emitted by an areal sample. The device ( 10 ) includes a support ( 11 ) transmitting all or part of the fluorescence signal and intended to support the areal sample ( 13 ), a thin layer ( 12 ) being interposed between the support ( 11 ) and the areal sample ( 13 ), the thin layer having a refractive index greater than the refractive index of the support and than the refractive index of the medium flooding the areal sample during a fluorescence measurement, the thickness of the thin layer being chosen so that the thin layer ( 12 ) transmits all or part of the fluorescence signal which is measured after passing through the support ( 12 ). |
