Abstract
A method and assembly for electrochemically identifying target nucleotide sequences. The method includes supplying a biological sample that may contain a predetermined target nucleotide sequence; supplying activatable amplification materials comprising free nucleotides to form replicated target nucleotide sequences; supplying an oxido-reducible compound capable of being inserted during replication between the nucleotides forming the replicated target sequences; and activating the activatable amplification materials before applying an electric field to the sample in order to activate the oxido-reducible compound. The replicated target sequences cause inhibition of electrochemical activity of the inserted oxido-reducible compound, and the presence of the predetermined target nucleotide sequence is determined in instances where the electric current decreases.
