Abstract (en)
[origin: WO2022053769A2] The invention relates to a device for detecting a target molecule (2) and/or measuring the concentration of a target molecule (2) comprising: a substrate at the surface of which is covalently attached a grafting molecule; at least one fluorescent probe (1) comprising: at least one receptor (11) bonded to a polypeptide (12) via a covalent bond; two fluorochromes Fa and Fb; in which the fluorochrome Fa is bonded to the receptor (11) and the fluorochrome Fb is bonded to the polypeptide (12); and the fluorochromes Fa and Fb form a FRET donor/acceptor pair; in which the polypeptide (12) is bonded to the grafting molecule via a covalent bond. The invention also relates to a fluorescent probe and a method for detecting a target molecule and/or measuring the concentration of a target molecule.
