Contrastive factors of activity and crowding on conformational properties of a flexible polymer

Activity and crowding effect is crucial in conformational change and relevant dynamics of biomolecules in complex environment, which remains a challenging problem. We perform a systematic Langevin simulation to investigate the conformational properties of a flexible polymer in an active bath. Firstly, we modulate both active force and bath particle size to probe the activity-induced polymer swelling. Results indicate a significant crowder size...
