Carbon nanotubes are intrinsically insoluble in aqueous solution. Since biological systems are composed of water-soluble structures, the solubilization of CNTs in aqueous solution is a prerequisite for their use in bioapplications. In addition, surface functionalization of CNTs with biologically active molecules is important to give them specific biological functions. Herein, we present systematic investigation of the combination self-assembly between the bioactive β-sheet block copolypeptides and CNTs. This type of self-assembly system includes force balance processes between two classes of completing forces: the attractive forces between β-sheet segments, and the attractive forces between β-sheet segments and CNTs. If the former predominates, the peptides construct β-sheet nanostructures while CNTs are still insoluble. On the other hand, water-soluble CNTs noncovalently functionalized with the bioactive β-sheet block copolypeptides can be constructed if the latter becomes dominan |
