摘要
Functionalisation of 2'-amino-LNA oligonucleotides with 1-, 2- and 4-(phenylethynyl)pyrene fluorophores via a carbonyl linker (PEPyc) resulted in efficient interstrand communication systems in nucleic acid duplexes, providing effective tools for stabilization of nanostructures and fluorescence monitoring of DNA self-assembly.
