Self-assembly and cell imaging behaviors of Tripeptide-naphthalenediimide and interactions with carbon nano-materials

Compared with other self-assembling molecule, peptide, especially unprotected peptide have better biocompatibility and are more acceptable for food science, cosmetics and biopharmaceuticals. However, the regulation of the microstructure formed by peptide self-assembled supramolecular remains a major problem.

However, the regulation of the microstructure formed by peptide self-assembled supramolecular remains a major problem. Herein we have designed three amphiphilic supramolecular that can self-assemble to form specific structures. The amphiphilic supramolecular use 1,4,5,8-naphthalenetetracarboxylic anhydride as the self-assembling framework to form some specific nanostructure by the regulation of the tripeptide molecule attached to both ends of the naphthalene diimide molecules. As designed, we have observed nanostructures such as spheres, squares, and needles formed under acidic or basic condition by electron microscopy images. And we attached the molecule to the carbon six-membered ring structure of carbon nanotubes and graphene, which provides a method for improving the dispersibility of carbon nanotubes and graphene. The peptide-based molecular designs enforce intimate π-π communication and hydrogen bonding within the aggregates after self-assembly, making these nanostructures attractive for optical or electronic applications in biological environments.at can self-assemble to form specific structures.
