Mussel inspired preparation of highly dispersible and biocompatible carbon nanotubes

Abstract

A novel method for preparation of water dispersible and biocompatible carbon nanotubes via mussel inspired PEGylation has been developed for the first time.

Preparation of amine functionalized carbon nanotubes via a bioinspired strategy and their application in Cu2+ removal

“…As compared with the pristine CNTs, the funcitonalized CNTs have demonstrated to be better performance in heavy metal ion removal [17,18]. Previously, a number of surface modification strategies such as surface oxidation with concentrated acid, non-covalent with surfactants and amphiphilic polymers, in situ polymerization and hybridized with inorganic nanomaterials have been reported [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34]. On the other hand, different physical methods such as plasma irradiation and gamma-irradiation have also developed for surface modification of CNTs.…”

Enhanced removal capability of kaolin toward methylene blue by mussel-inspired functionalization

“…It is well-known that the selfpolymerization of dopamine can coat on a large number of material surfaces for the adhesion of PDA. More importantly, the PDA coatings can provide an active platform for further surface modification through different strategies including surface initiated polymerization, free radical polymerization, and Michael addition reaction [42][43][44][45][46][47][48]. In this work, the PSPSH polymer terminated with amino group was first synthesized via free radical polymerization using cysteamine hydrochloride as the chain transfer agent and SPSH as the monomer.…”

A bioinspired strategy for surface modification of silica nanoparticles

“…For example, Lu et al have demonstrated that PDA nanospheres can be heated by near infared (NIR) laser and exhibited better photothermal effect than that of gold nanoparticles [65]. On the other hand, our recent report suggested that surface modification of carbon nanotubes with PDA and PEG can obviously improve the dispersibility and biocompatibility of carbon nanotubes [76]. The possible mechanism for enhanced biocompatibility is partly due to the PEG coating and the free radical scavenging capability of PDA coating.…”
