1. A method of synthesizing a stabilized polymersome, comprising:
- forming a polymersome, having a layer structure, from chains of multiblock copolymer comprising hydrophobic and hydrophilic blocks;
at least some of the hydrophobic blocks comprising one or more polymerizable groups; and
reacting two or more of the polymerizable groups to form covalent bonds between chains of the copolymer.
