BIOSENSOR, DEVICE AND METHOD FOR DETECTING NUCLEIC ACIDS BY MEANS OF AT LEAST TWO UNITS FOR IMMOBILIZING NUCLEIC ACIDS

摘要

The invention relates to a biosensor for detecting nucleic acids, comprising at least two units for immobilizing nucleic acids and one electrical detection circuit. Said units are electroconductive and electrically insulated from one another. The units are provided with first nucleic acid molecules that are present as single-stranded molecules and that are capable of binding second nucleic acids to be detected. These scavenger molecules are provided with a redox-active marker that is capable of producing a detectable signal. The electrical detection circuit is adapted to detect by means of the marker any nucleic acid molecules bound to the scavenger molecules.
