A Discrete Self-Assembled Metal Array in Artificial DNA

Abstract

DNA has a structural basis to array functionalized building blocks. Here we report the synthesis of a series of artificial oligonucleotides, d(5′-G H n C-3′) ( n = 1 to 5), with hydroxypyridone nucleobases ( H ) as flat bidentate ligands. Right-handed double helices of the oligonucleotides, n Cu 2+ ·d(5′-G H n C-3′) 2 ( n = 1 to 5), were quantitatively formed through copper ion (Cu 2+ )–mediated alternative base pairing ( H -Cu 2+ - H ), where the Cu 2+ ions incorporated into each complex were aligned along the helix axes inside the duplexes with the Cu 2+ -Cu 2+ distance of 3.7 ± 0.1 angstroms. The Cu 2+ ions were coupled ferromagnetically with one another through unpaired d electrons to form magnetic chains.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
