| 摘要 |
The invention relates to an agent for detecting chemical substances, comprising: a first polynucleotide or peptide sequence having a first fluorophore molecule, the first end of said sequence being bonded on a solid phase and a second polynucleotide or peptide sequence having a second fluorophore molecule, the second end of said sequence having a group that is sensitive to the chemical substance to be detected. The first polynucleotide or peptide sequence can be hybridized to the second polynucleotide or peptide sequence in such a way that a spatial relationship enabling an interaction betweeen the first and the second fluorophore molecule is produced. When the chemical substance including a physical property is attached to the group and the influence of an external force is exerted on the physical property, the spatial relation can be eliminated, thereby generating or abolishing a fluorescent reaction.
