Interaction modes between copolymer and DOTAP revealed by Langevin dynamics simulation in water. (A) The initial conformation of FA-PEG-PLA copolymer complexed with DOTAP. Conformations (B), (C), (D), (E), and (F) correspond to snapshots of the complex collected at 100 ps, 200 ps, 300 ps, 400 and 500 ps, respectively. Copolymer FAMPEG-PLA is represented by a thin line. DOTAP is depicted by a thick line, and its carbon atoms are colored green. Two terminal heavy atoms in the FA-PEG-PLA copolymer are highlighted using a “ball” style.
