Patent ID: 7157230

Claim:
A method of sequencing a target nucleic acid comprising: obtaining the target nucleic acid; hybridizing the nucleic acid to a probe library comprised of at least 256 distinguishably labeled different probe, wherein the probes are labeled with conductive polymers, wherein the conductive polymers are selected from the group consisting of polyaniline, polyphenylene-vinylene, polythiophene, polypyrrole, polyacetylene, polydiacetylene, polytriacetylene, poly-p-phenylene, polyfuran, betacarotene, a substituted polyaniline, a substituted polyphenylene-vinylene, a substituted polythiophene, a substituted polypyrrole, a substituted polyacetylene, a substituted polydiacetylene, a substituted polytriacetylene, a substituted poly-p-phenylene, a substituted polyfuran, a substituted betacarotene and a conjugated oligomer, and wherein the substitution is an alkoxy side chain, an alkyl side chain or an aryl side chain; separating the hybridized nucleic acid from unhybridized probes; and detecting the order of hybridized probes along the nucleic acid.
