PEG (5k) (blue lines)-ASP (35 units) (red lines) CNA preparation. 1) PEG-ASP(H+) block copolymers were cross-linked (green lines) with diaminooctane (DAO) activated with diisopropylcarbodiimide (DIC)/ N-hydroxysuccinimide (NHS)/dimethylaminopyridine (DMAP); 2) ASP(H+) groups of PEG-ASP CNAs converted to ASP(Na+); 3) positively charged Ru complexes (red circles) were physically entrapped inside PEG-ASP CNAs through electrostatic interactions with ASP(Na+) groups.
