Beschreibung
Zusammenfassung:	The invention relates to an analytical support for determining an analyte such as a DNA or RNA target, by carrying out a specific reaction of binding (hybridization) of said analyte with a ligand specific for this analyte, and determining the binding reaction by means of at least two fluorescent labels present on the analyte. This determination is carried out by applying an excitatory field and detecting the fluorescent emission of the various fluorescent labels. According to the invention, the support comprises a substrate coated with one or more layers of material(s) forming an assembly capable of decreasing or increasing the excitatory field for at least one of the fluorescent labels compared to the others. The ligands are attached to the final layer of the assembly. A layer of SiO2 on a substrate of silicon can be used with the fluorescent labels Cy3 and Cy5.
