Enhancing surface-generated fluorescence signal emitted by a sample

摘要

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).
