pH-induced morphology-shifting of DNA-b-poly(propylene oxide) assemblies.
The designed DNA sequences can make DNA-b-PPO undergo in situ transition between diblock and triblock upon pH changes, consequently, induce a morphology-shifting from spherical micelles to nanofibers. This process is reversible and the assembled structures have been characterized by CD, TEM and fluorescent experiments.
