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 کاملMultiple functionalization of single-walled carbon nanotubes by dip coating.
Single walled carbon nanotubes were functionalized with different functionalities by simple dip coating. This fast and reproducible procedure was realized with nanotube coated electrodes for the construction of polyvalent biosensors. Three different pyrene derivatives were attached to the nanotube sidewalls by π-stacking interactions in a one-step reaction.
متن کاملChemical Detection Using Single - Walled Carbon Nanotubes
We have developed electronic devices and sensors that use two-dimensional random networks of SWNTs as the active electronic material [1]. Such network devices display the aggregate properties of many randomly distributed SWNTs and can be processed into devices of arbitrary size using conventional microfabrication technology. We report here on the results of our efforts to develop chemical senso...

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 کاملReversible functionalization of multi-walled carbon nanotubes with organic dyes
Multi-walled carbon nanotubes are dispersed in water via the formation of adducts with dyes, where the process may be monitored by the visual observation of colour variations of dye solutions. Atomic force microscopy images corroborate evidence for attachment of dyes on nanotubes. Laser Raman and Fourier transform infrared spectroscopies suggest intimate electronic interactions between nanotube...
