Block copolymer crystalsomes with an ultrathin shell to extend blood circulation time

Nature Communications, 2018
In block copolymer vesicles, crystallization often leads to defects and renders the structures leaky that undermines their potential biomedical application. Here the authors use an emulsion solution method to control the crystallization of an amphiphilic
