Well-Defined DNA Nanoparticles Templated by Self-Assembled M12L24 Molecular Spheres and Binding of Complementary Oligonucleotides

摘要

Perfectly monodisperse DNA nanoparticles were prepared via the self-assembly of 12 Pd(II) ions and 24 bidentate ligands functionalized with oligonucleotides of varying length (n = 1−3). The DNA nanoparticles formed hydrogen bonds with cDNA strands and an insoluble aggregate formed only with matching trimeric nucleotide strands (tri-A).
