Chemical structures of homopolymers and block copolymers used in this study. PLys (A,B) is cationic and hydrophilic, where PVBTMA (D,E) is also cationic but hydrophobic. PEG blocks (B,E) are neutral and hydrophilic. These polymers complex with DNA oligonucleotides (C), which are anionic and hydrophilic, to form phase-separated assemblies.
