Adherent Moving of Polymers in Spherical Confined Binary Semiflexible Ring Polymer Mixtures

Based on the coarse-grained model, we used molecular dynamics methods to calculate and simulate a semiflexible long ring–semiflexible short ring blended polymer system confined in hard sphere. We systematically studied distribution motion characteristics of chain. The results show that when is enough (Lshort < 20), (Llong = 50) separated from blend then distributed against inner wall. As length increases ≥ can no longer be blending system. Moreover, found demonstrates random direction adherent walking behavior surface velocity decreases with increase Lshort. Specifically for Lshort 20, does not undergo phase separation speed sharply along inside bulk. This related wall layer moving faster than bulk restricted Our simulation help us understand macromolecules biological systems systems, including chromosome partitioning packing structure circular DNA molecules.
