Single-walled carbon nanotubes (SWCNT) functionalized with amino groups were prepared via chemical modification of carboxyl groups introduced on the carbon nanotube surface. Two different approaches (amide and amine-moieties) were used to produce the amino-functionalized nanotubes. The aminotermination allows further chemistry of the functionalized SWCNTs and makes possible covalent bonding to ...

We report the effect of chemical modification of multi-walled carbon nanotubes (MWNTs) on their activation of the human serum complement system, as well as the adsorption of human plasma proteins on MWNTs. Four different types of chemically-modified MWNTs were tested for complement activation via the classical and alternative pathways using haemolytic assays. Human plasma protein binding was al...

Multi-walled carbon nanotubes (MWCNTs) are known as efficient drug carriers. To improve their interaction with other materials, surface modification of MWCNTs is necessary. In this work, were functionalized acid and polysaccharides (chitosan gelatin). The functionalization process was done via solutions nitric acid, sulfuric a mixture acid-sulfuric first, followed by chitosan gelatin. achieve t...

We demonstrate that the functionalization of carbon nanotubes dramatically alters their sorption characteristics. The effect of covalent functionalization of multiwalled carbon nanotubes (MWNTs) on the gas phase adsorption and desorption of polar and nonpolar organics is presented. Carboxylation and nitration led to the generation of polar functional groups on the nanotube surface. The derivati...

Multi-walled carbon nanotubes (MWCNTs) were functionalized using nonequilibrium atmospheric pressure plasma. The efficiency of the atmospheric pressure plasma treatment is characterised by XPS, FT-IR spectroscopy and contact angle measurements. Scanning electron microscopy (SEM) reveals that the MWCNT structure can be preserved when wet feeding into the plasma is applied.

In this study we compare the biodegradation of both single-walled (SWCNTs) and multi-walled carbon nanotubes (MWCNTs) using two different oxidative conditions. In particular, we demonstrate that oxidized multi-walled carbon nanotubes are highly degraded, although not to completeness when treated with horseradish peroxidase (HRP) in the presence of hydrogen peroxide.

Recent advances in the field of biomedical have been remarkably achieved last few years, especially fabrication nanomaterials that various applications. Carbon nanotubes (CNTs) are carbon-based materials with cylindrical shapes an average diameter less than 2 nanometre (nm) for single-walled CNTs (SWCNTs) and multi-walled (MWCNTs) diameters up to 100 nm. demonstrate outstanding excellent mechan...
