“Background The last decade has seen a great deal of activity in the use of carbon nanotubes (CNTs) to augment the properties of a variety of materials, including biomaterials [1]. The advantage of carbon nanotubes in biomedicine is their stable conductivity in aqueous physiological environment, thus making them attractive for cellular stimulation [2]. And, the weakness of raw CNTs is their super-hydrophobicity. They can easily aggregate in aqueous media as well as in organic solvents, which strictly restricts their application
in biomedical fields because a hydrophilic interface is in favor of enhancing bioactivity [3]. So, in recent years, the enormous progress in nanotechnology and material sciences had stimulated the development and production of engineered carbon nanotubes [4–9]. And, numerous studies in biomaterial development indicated the functionalized water-soluble CNTs to improve cell attachment and growth [5–9]. In our previous work [10], the ATR inhibitor improved hemocompatibility and cytocompatibility were also observed in N-doped MWCNTs when compared with pristine MWCNTs using chemical vapor deposition (CVD) method. Recently, many studies on the functionalization of MWCNTs have been reported. Chemical grafting is the main method for CNT functionalization.
