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 کاملEnhancement of lipase activity in non-aqueous media upon immobilization on multi-walled carbon nanotubes
BACKGROUND Immobilization of biologically active proteins on nanosized surfaces is a key process in bionanofabrication. Carbon nanotubes with their high surface areas, as well as useful electronic, thermal and mechanical properties, constitute important building blocks in the fabrication of novel functional materials. RESULTS Lipases from Candida rugosa (CRL) were found to be adsorbed on the ...
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 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...
متن کاملAsymmetric end-functionalization of multi-walled carbon nanotubes.
Asymmetric end-functionalization of carbon nanotubes was achieved by sequentially floating a substrate-free aligned carbon nanotube film on two different photoreactive solutions with only one side of the nanotube film being contacted with the photoreactive solution and exposed to UV light each time. The resultant nanotubes with different chemical reagents attached onto their opposite tube-ends ...
