Schematic representation of the self-assembly of four amphiphilic diblock copolymers into non-ionic micelle (1), anionic micelle (2), cationic micelle (3) and zwitterionic micelle (4) and the shell-crosslinking of resulting three charged micelle into anionic SCKs (5), cationic SCKs (6) and zwitterionic SCKs (7).
