概要

Block ionomer complexes are spontaneously formed by reacting the block (or graft) copolymers containing hydrophilic non-ionic and ionic polymeric segments (“block ionomers”) with oppositely charged species such as polyions, proteins, surfactants, or metal ions. These complexes self-assemble into particles of nanoscale size and form stable aqueous dispersions. The latter enable, uniquely, encapsulation of charged therapeutic molecules. The pH- and salt-sensitivity of such block ionomer complexes provide a unique opportunity to control the triggered release of the active therapeutic agent. The block ionomer-metal complexes can be used as templates to synthesize a novel type of entirely hydrophilic polymer micelles with cross-linked ionic cores. These core-shell materials represent nanosized gels with the core comprising a swollen network of crosslinked polyions surrounded by a nonionic polymer shell. The potential applications of such cross-linked micelles as nanocarriers for drugs and imaging agents will be discussed.
