Interaction modes between FA-PEG-PLA copolymer and DOTAP revealed by Langevin dynamics simulation near 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 PEG and PLA are depicted with a solid surface and colored by elements and green, respectively.
