  • Patent number: 8409797
    Abstract: An optical sensor for detecting a target comprising a singlestranded aptamer complementary to said target, and a water-soluble cationic polythiophene derivative of the following formula: wherein ā€œnā€ is an integer ranging from 6 to 100, is disclosed. The optical sensor allows for the detection of targets selected from the group consisting of potassium ions, small organic molecules, amino acids, proteins, whole cells and nucleotides. The detection is based on the formation of hybrid anionic aptamer/cationic poly-thiophene complexes.

  • Patent number: 7972860
    Abstract: The present invention relates to a novel integrated PCR-free signal amplification polynucleotide detection system which combines a specific receptor, an optical transducer, and an amplification mechanism. This novel detection system is based on different electrostatic interactions and confirmations between a cationic polythiophene (i.e., polymer 1) and single-stranded or double-stranded polynucleotides (such as ss-DNA or ds-DNA), and the efficient energy transfer between the triplex (complexation between the cationic polythiophene and ds-DNA) and neighboring fluorophores attached to ss-DNA or ds-DNA probes. It is to be understood that in the case of ss-DNA, triplex formation occurs via the hybridization of complementary ss-DNA strands, combined with complexation and with the cationic polythiophene. The present detection system allows for the detection of single nucleotide polymorphisms (SNPs) from samples in only a few minutes, without the need for nucleic acid amplification.

  • Patent number: 7897348
    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.
