چکیده
The unique (n, m) SWCNTs have both left- and right-handed helicity and they are enantiomers, and unique chiral SWCNTs with single helicity haven't achieved yet. In our studies the aromatic fluorescence molecule, (R+) 5'-Hexachloro-Fluorescein Phosphoramidite (HEX), was linked to DNA, and this new polymer could help us to get unique chiral SWCNT (11,1) with only right-handed species, and this result is confirmed by AFM, HRTEM, NIR, SRCD, and Raman studies.

Probing the structure of DNA-carbon nanotube hybrids with molecular dynamics.
DNA-carbon nanotube hybrids (DNA-CN) are novel nanoscale materials that consist of single-wall carbon nanotubes (SWCN) coated with a self-assembled monolayer of single-stranded DNA (ssDNA). Recent experiments on DNA-CN have shown that this material offers a remarkable set of technologically useful properties such as facilitation of SWCN sorting, chemical sensing, and detection of DNA hybridizat...
متن کاملAb Initio Study of Chirality Effects Onphonon Spectra, Mechanical and Thermal Properties of Nearly Samediameter Single Wall Carbon Nanotubes
In this paper, we have used density functional perturbation theory (DFPT) and Pseudo-potential method to calculate the phonon spectrum, phonon density of states (DOS), specific heat capacity and mechanical properties of (5,5) armchair and (9,0) zigzag Single Wall Carbon Nanotubes (SWCNTs). Our calculations show that Young’s modulusfor (5,5) and (9,0) nanotubesare higher than 1TPa. We have also ...
متن کاملThe Attitude of Variation of Elastic Modules in Single Wall Carbon Nanotubes: Nonlinear Mass-Spring Model
The examination of variation of elastic modules in single wall carbon nanotubes (SWCNTs) is the aim of this paper. Full nonlinear spring-like elements are employed to simulate specific atomic structures in the commercial code ABAQUS. Carbon atoms are attached to each node as a mass point using atomic mass of carbon atoms. The influence of dimensions such as variation of length, diameter, aspect...

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...
متن کاملTheory of Electronic and Optical Properties of DNA-SWNT Hybrids
Single-wall nanotubes (SWNTs) are being studied for use as components in the next generation of electronic and optical devices, including transistors, photodetectors, and biological sensors [1], but to realize large scale production of these and other potential devices, methods must be developed to gain control over the material. This task is multifaceted. Firstly, as-synthesized carbon nanotub...
