Patents by Inventor Damien Marchal

Damien Marchal has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9856526
    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.

  • Patent number: 8313638
    Abstract: The invention relates to a method and a collection for the electrochemical detection of target nucleic acid sequences. According to the method, a biological sample that may contain a nucleic acid is provided, said nucleic acid being capable of containing a target sequence, said biological sample being mixed with an oxidizing agent, said target sequence comprising at least one nucleotide base that can be oxidized by said oxidizing agent; complementary means capable of coupling with said target sequence are provided; according to the invention, said complementary means comprise activatable amplification means suitable for replicating said target sequence, said amplification means comprising at least nucleotides which include said nucleotide base, wherein said nucleotides are able to be consumed during replication so as to constitute replicated nucleic acids; and the presence of said target sequence is determined by applying an electric field to said sample and recording the decrease in the electric current.

    Abstract: The present disclosure relates to a method and assembly for electrochemically identifying target nucleotide sequences. The method includes the following steps consisting of: supplying a biological sample that may contain a predetermined target nucleotide sequence; supplying activatable amplification means comprising free nucleotides in order 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 means before applying an electric field to the sample in order to activate the oxido-reducible compound. Said replicated target sequences then cause the inhibition of the electrochemical activity of the inserted oxido-reducible compound, and the presence of the predetermined target nucleotide sequence is determined if the electric current decreases.
