Patent ID: 7019830

Claim:
A process for at least one of a qualitative analysis and a quantitative analysis of an analyte in a solution, the process comprising: on an arrangement structure on which a first chromophore is disposed which is capable of emitting a fluorescent light of a wavelength λ 1 in response to irradiation of the first chromophore with an electro-magnetic radiation, which causes the first chromophore to absorb a wavelength λ, and the first chromophore being interconnected by an elastic coupling with a second chromophore at a spacing relative to the second chromophore such that a fluorescence resonance energy transfer (FRET) is possible between the second chromophore and the first chromophore, the second chromophore being capable of emitting a fluorescent light of a wavelength λ 2 in response to a transfer of light in a non-direct irradiation manner to the second chromophore and the second chromophore being connected to a ligand having the analyte coupled thereto, irradiating the first chromophore with an electro-magnetic radiation while simultaneously moving the arrangement structure 1 and the analyte relative to one another in a manner which effects extension of the elastic coupling interconnecting the first chromophore and the second chromophore; measuring the intensities of the fluorescent light having the respective wavelength λ 1 and the fluorescent light having the respective wavelength λ 2 during the movement of the arrangement structure and the analyte relative to one another; and determining at least one of the type and the amount of the analyte as a function of the intensities of the fluorescent light having the respective wavelength λ 1 and the fluorescent light having the respective wavelength λ 2 which have been monitored during the movement of the arrangement structure and the analyte relative to one another.
