چکیده

We have covalently coupled single-walled carbon nanotubes (SWNTs) to peptide nucleic acid (PNA, a synthetic DNA analogue [1]), and shown that the resulting macromolecular wires hybridize with complementary DNA. This provides a powerful tool to incorporate SWNTs into a recognition-based, massively parallel device assembly strategy, and permits sequence-specific attachment of SWNTs to biological complexes.

Investigation of Solvent Effects on Interaction of Single-Strand DNA with Open-End of Single Walled Carbon Nanotubes Using QM and MM methods

The interaction of biomolecules with carbon nanotubes (CNTs) has generated a great deal ofinterest in the past few years. The interaction between B-form single-strand DNA (ssDNA) andsingle-walled carbon nanotubes (SWCNTs) is a subject of intense current interest; however thereare a relatively small number of papers in the literature dealing with interaction of DNA andSWCNTs. In this work we inv...

DNA origami templated self-assembly of discrete length single wall carbon nanotubes.

Constructing intricate geometric arrangements of components is one of the central challenges of nanotechnology. Here we report a convenient, versatile method to organize discrete length single-walled carbon nanotubes (SWNT) into complex geometries using 2D DNA origami structures. First, a size exclusion HPLC purification protocol was used to isolate uniform length, SWNTs labelled with single st...
