Self-assembled organic nanotubes: Architectures and nano-bio functions

Certain amphiphilic molecules, which were rationally designed, have been found to produce tubular structures with well-defined dimensions and morphologies through molecular self-assembly. In particular, organic nanotubes with inner and outer surfaces covered with different chemical functionalities are able to encapsulate and release a protein guest in aqueous solutions. The resultant organic nanotubes have proved to be of significant importance for potential biological, medical, and industrial applications.
