Schematic illustration of PBAE synthesis and nanoparticle surface modification. (a) General scheme for synthesis of PBAE copolymer through Michael addition reaction. Amine groups are highlighted in green. (b) Formation of PBAE-DOX through reaction between DEGDA, PEG, DA and DOX. Note: this illustration does not reflect the exact sequence and ratio of each component. (c) Formation of NP-DOX via ligand-exchange reaction.
