Multiplexed detection of nucleic acids using 19 F NMR chemical shift changes based on DNA photo-cross-linking of 3-vinylcarbazole derivatives.

The detection methodology for nucleic acids is a useful tool for the analysis of biological systems and diagnosis of diseases. We demonstrated the feasibility of the detection of any nucleic acids based on large chemical shifts via ultrafast DNA photo-cross-linking and the effects of substitution by 3-vinylcarbazole derivatives. These chemical shifts enable the sequence-specific detection of any strand using hybridization chain reaction.
