Bio-functionalization of multi-walled carbon nanotubes.
Here we present a hybrid approach to functionalize multi-walled carbon nanotubes in aqueous solution, exploring a non-covalent binding strategy. We focus on formation of hybrid complexes consisting of carbon nanotubes decorated by single stranded DNA, non-covalently attached using surfactants as intermediate layers. Unlike single walled carbon nanotubes, revealing easy side wall wrapping of DNA...
متن کاملProteomics-based safety evaluation of multi-walled carbon nanotubes.
This study evaluated the biological responses to multi-walled carbon nanotubes (MWCNTs). Human monoblastic leukemia cells (U937) were exposed to As-grown MWCNTs and MWCNTs that were thermally treated at 1800 degrees C (HTT1800) and 2800 degrees C (HTT2800). Cell proliferation was highly inhibited by As-grown but not HTT2800. However, both As-grown and HTT1800, which include some impurities, wer...
متن کاملSupporting information Bio-functionalization of Multi-walled Carbon Nanotubes
1. Comparative study of carbon nanotube dispersion using surfactants Aqueous carbon nanotube dispersions were obtained by sonication tip using two cationic (DTAB and CTAB) and three anionic surfactants (SDDBS, SDS and SC). UV-Vis spectroscopy is a versatile method for characterizing the dispersion quality of CNTs in a solution. Bundles of MWCNTs are not active in the wavelength region between 2...
متن کاملnano-qsar: genotoxicity of multi-walled carbon nanotubes
the study was carried out to develop an efficient approach for prediction the genotoxicity of carbon nanotubes. the experimental data on the bacterial reverse mutation test (ta100) on multi-walled carbon nanotubes (mwcnts) was collected from the literature and examined as an endpoint. by means of the optimal descriptors calculated with the monte carlo method a mathematical model of the endpoint...
متن کاملContinuum models of multi-walled carbon nanotubes
Molecular mechanics (MM) simulations have been carried out to determine energetically favorable double-walled carbon nanotube (DWNT) structures, and analyze their infinitesimal extensional, torsional, radial expansion/contraction, and bending deformations. Loads are applied either to one wall or simultaneously to both walls of an open-ended DWNT. These results are compared against single-walled...
