| abstract |
The invention relates to a method for detecting and quantifying a first biomolecule in a solution (5, 8), comprising the following steps: a) binding of the first biomolecule (5, 8) to a second biomolecule (3, 7) which at least along segments thereof exhibits a specific affinity to a first biomolecule and b) determination of the electrical conductivity of a complex formed from the first (3, 7) and the second biomolecule (5, 8), whereby the second biomolecule (3, 7) forms a bridge between a first 2a and a second electrode 2b. |
