DNA pillars constructed from an i-motif stem and duplex branches.

At an acidic pH, cytosine-rich DNA strands can form i-motif tetramers. Pillar-like DNA structures are self-assembled with such i-motifs as the central stems. The central stem has some overhanging structures that can enable hybridization with complementary units by Watson-Crick pairing and, thus, multiple i-motifs can join to form the pillar.

Improving the yield of mono-DNA-functionalized gold nanoparticles through dual steric hindrance.

A novel strategy of dual steric hindrance, which was obtained by Janus modification of gold nanoparticles (Au NPs) and volume exclusion of DNA, was adopted to prepare mono-DNA-modified Au NPs. The yield of mono-DNA-functionalized Au NPs significantly improved from 44 to 70% in the reaction between Au NPs and thiolated DNA. Furthermore, the specificity of mono-DNA-functionalized Au NPs was enhanced from 57 to 95%.

DNA-SWNT hybrid hydrogel.

In this communication, we report the preparation of DNA-SWNT hybrid hydrogel which is pH responsive and strength tunable.

pH-controlled carbon nanotube aggregation/dispersion based on intermolecular i-motif DNA formation.

In this work, we report a new strategy to manipulate the aggregation and dispersion of carbon nanotube in solution via formation of intermolecular i-motif (four-stranded C-quadruplex) structures in a pH dependent manner. Firstly, single-stranded (ss) DNAs containing two stretches of cytosine (C)-rich domains are covalently linked to carbon nanotubes. At pH 8.

A pH-driven, reconfigurable DNA nanotriangle.

A simple and robust DNA nanotriangle that can be conveniently reconfigured by environmental pH changes is demonstrated.

DNA-templated CMV viral capsid proteins assemble into nanotubes.

This communication describes the in vitro assembly of genetically recombinant Cucumber Mosaic Virus (CMV) viral capsid proteins (CPs) into biological nanotubes, several micrometres long yet with a diameter of only approximately 17 nm, triggered by double-stranded DNAs of different lengths.
