Making carbon nanotubes biocompatible and biodegradable.
Carbon nanotubes are promising nanomaterials with great potential in the field of nanomedicine for both therapeutic and diagnostic applications. Different approaches have been developed to render this material biocompatible and to modulate any ensuing toxic effects. In the context of medical use, although chemically functionalised carbon nanotubes display reduced toxicity, they are still consid...
متن کاملMicrowave-Assisted Modification of Carbon Nanotubes with Biocompatible Polylactic Acid
Polylactic acid (PLA) was successfully covalently grafted onto multi-walled carbon nanotubes (MWCNT) by microwave-assisted polymerization of lactide monomers. The final products MWCNT-g-PLA were characterized with Fourier-transform IR (FTIR), Raman spectroscopy, thermogravimetric analyses (TGA) and transmission electron microscopy (TEM). The results indicated PLA chain was covalently attached t...
متن کاملDJ-1 as a potential biomarker for the development of biocompatible multiwalled carbon nanotubes
BACKGROUND In the present study, we investigated whether DJ-1 could serve as a biomarker for assessing the biocompatibility of multiwalled carbon nanotubes (MWCNTs), using the highly purified carbon nanotube, HTT2800. METHODS Using Western blot analysis, we determined DJ-1 protein levels in two different types of cells (one capable and the other incapable of HTT2800 endocytosis). Using quanti...
متن کاملHighly efficient exfoliation of individual single-walled carbon nanotubes by biocompatible phenoxylated dextran.
Highly efficient exfoliation of individual single-walled carbon nanotubes (SWNTs) was successfully demonstrated by utilizing biocompatible phenoxylated dextran, a kind of polysaccharide, as a SWNT dispersion agent. Phenoxylated dextran shows greater ability in producing individual SWNTs from raw materials than any other dispersing agent, including anionic surfactants and another polysaccharide....
متن کاملNovel biocompatible chitosan decorated single-walled carbon nanotubes (SWNTs) for biomedical applications: theoretical and experimental investigations.
Molecular mechanics and molecular dynamics simulations have been employed to characterise the interactions between SWNTs and biocompatible amphililic derivatives of chitosan, namely N-butyl-O-sulfate chitosan (NBSC), N-octyl-O-sulfate chitosan (NOSC) and N-palmitoyl-O-sulfate chitosan (NPSC). The computational simulations have shown that the affinity of the polymer for the hydrophobic surface o...
