Nanotechnologies require a detailed knowledge of the molecular state. For instance, it is useful to know when and how a generic polymer, a long chain of polymers (chain of beads), knots. The study of molecular entanglement is an important field of study as the presence of knots affects its physical properties, for instance the resistence to traction. Previous studies had mainly obtained “static” data on the knotting probability of such molecules. In other words, they focused on the likelihood that a polymer may knot. The novelty of the new study lies in the fact that this time the dynamic aspect of the phenomenon has been simulated.
