Distance from membrane. (a): The distance of PE monomer from the POPC membrane atoms plotted with respect to simulation time in a single selected example simulation run. Figure shows random movement in water at first until at 22 ns the molecule moved inside the membrane, exited at 35 ns and did another enter and exit between 52 and 78 ns. (b): PET monomer showed random movement in water at first but entered the membrane at 30 ns and remained there until the end of the simulation.
