Patents by Inventor Hoang Ahn Ho

Hoang Ahn Ho 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).

  • Detection of negatively charged polymers using water-soluble, cationic, polythiophene derivatives
    Patent number: 7601503
    Abstract: Novel methods allowing for the simple optical and electrochemical detection of double-stranded oligonucleotides are disclosed. The methods are rapid, selective and versatile. Advantageously, they do not require any chemical reaction on the probes or on the analytes since they are based on different electrostatic interactions between cationic poly(3-alkoxy-4-methylthiophene) derivatives and single-stranded or double-stranded (hybridized) oligonucleotides.
    Type: Grant
    Filed: October 7, 2008
    Date of Patent: October 13, 2009
    Assignee: GeneOhm Sciences Canada, Inc.
    Inventors: Mario Leclerc, Hoang Ahn Ho, Maurice Boissinot
