Abstract
AbstractThe programmability of oligonucleotide recognition offers an attractive platform for directing the assembly of ligands that can interact cooperatively with a target or the assembly of reactive partner that can engage in chemical reactions. In both cases, an oligonucleotide directs the assembly, which yields a functional output. In terms of the controlled display of ligands, several examples have shown a significant increase in binding upon ligand assembly using small molecule fragments, peptides, glycans, and protein fragments. Combinatorial approaches to identifying the optimal pairing have also been reported. In terms of nucleic acidtriggered reactions, several robust chemistries have been reported, leading to the unmasking of different fluorophores or bioactive molecules as well as the synthesis of a bioactive compound in response to DNA or even cellular RNA. Herein we present the historical context of this work and summarize recent developments in this area.
