Optical detection and discrimination of cystic fibrosis-related genetic mutations using oligonucleotide-nanoparticle conjugates.

Abstract excerpt

Novel methods for application of oligonucleotide-gold nanoparticle conjugates to selective colorimetric detection and discrimination of cystic fibrosis (CF) related genetic mutations in model oligonucleotide systems are presented. Three-strand oligonucleotide complexes are employed, wherein two probe oligonucleotide-gold nanoparticle conjugates are linked together by a third target oligonucleotide strand bearing...
