Sub-picomole colorimetric single nucleotide polymorphism discrimination using oligonucleotide-nanoparticle conjugates.

Abstract excerpt

Oligonucleotide-gold nanoparticle conjugates are employed to demonstrate selective colorimetric discrimination of a cystic fibrosis-related genetic mutation in a model oligonucleotide system. Specifically, three strand oligonucleotide complexes are employed, wherein two probe oligonucleotide-gold nanoparticle conjugates are linked together by a third target oligonucleotide strand bearing the chosen CF-related...
