 >Getting interlocked circular chains through the needle’s eye</a>\nby En
 zo Orlandini (Physics U. Padova - Italy) as part of GEOTOP-A seminar\n\n\n
 Abstract\nThe process of driven translocation of polymer chains through a 
 narrow pore can be severely hindered by the presence of self and mutual en
 tanglement. In circular chains this entanglement is trapped in the form of
  knots and links that may act as potential obstruction at the pore affecti
 ng the translocation dynamics. Here we present theoretical results mainly 
 based on extensive Langevin simulations on the driven translocation dynami
 cs of topologically linked rings. We highlight the role of link complexity
 \, pore size and driving force field  on the translocation process and sug
 gest how to extend nanopore sensing techniques to probe the topological pr
 operties of these systems and\, for instance\, to distinguish knotted from
  linked states and two component to multicomponent links.\n
