Recent Progress on Nanostructures for Drug Delivery Applications

Schematic representation of the multiscale self-assembly of the FF-microtubes and their conjugation to rhodamine. Stacked FF hexamers form honeycomb-like arrays, which give rise to nanotubes. Subsequently, these nanotubes cluster into larger microtubes. The inner surfaces of the nanotubes exhibit both hydrophobic and hydrophilic groups, with the latter being able to trap polar species [8]. Copyright © 2013, American Chemical Society.
