Chelation competition induced polymerization (CCIP): construction of integrated hollow polydopamine nanocontainers with tailorable functionalities.

A novel 'chelation competition induced polymerization' route was developed to construct hollow polydopamine nanocontainers with tailorable functionalities. The mechanism is systematically investigated and the nanocontainers constructed through this method show excellent chemo-thermo performance in vitro. This strategy is facile and is expected to be used for the construction of a series of hollow polymer nanostructures.
