| 摘要 |
The invention relates to an agent for detecting chemical substances or physical properties, comprising: a first polynucleotide (1) or peptide sequence having a first (3) fluorophore group, the first end (E1) of said sequence being bonded on a solid phase (5) and a second polynucleotide (1a) or peptide sequence having a second (4) fluorophore group, the second end (E2) of said sequence having a group (6) that can be bonded or attached to the chemical substance (7) to be detected or that is sensitive to the physical property to be detected. The first polynucleotide (1) or peptide sequence can be attached to the second polynucleotide (1a) or peptide sequence in such a way that a spatial relationship enabling an interaction between the first (3) and the second fluorophore group (4) is produced. When the chemical substance (7) is attached to the group (6) and or the influence of an external force is exerted on the group (6, 12), the spatial relation can be eliminated thereby generating a fluorescent reaction.
