Recent progress in specific recognition and modulation of DNA by nano-metallo-supramolecular complexes

There is great interest in design and synthesis of ligands which selectively target specific genes to inhibit biological functions in which particular DNA structures participate. Among these studies, DNA structural recognition and functional regulation by metal complexes have received much attention because several metal complexes have shown specific interactions with DNA secondary structure and even regulation of DNA biological functions. Recent studies have demonstrated that metallo-supramolecular complexes with nanoscale can recognize different DNA structures and exhibit special preference. This review summarizes recent progress in nano-metallo-supramolecular complexes binding to various DNA secondary structures and their selectivity and specificity.
