Controllable peptide-dendron self-assembly: interconversion of nanotubes and fibrillar nanostructures.

Roll up: A peptide-dendron hybrid (PDH) is capable of self-assembling into either a soluble nanotube or an amyloid-like fibrillar network. The structures interconvert on adjusting the salt concentration or pH value. Their hydrophobic interfaces efficiently encapsulate hydrophobic molecules in water which can then be released by lowering the pH value.
