Current approaches to generate core-shell nanoparticles for biomedical applications are limited by factors such as synthetic scalability and circulatory desorption of cytotoxic surfactants. Developments in controlled radical polymerization, particularly in dispersed states, represent a promising method of overcoming these challenges.
