Abstract
In this thesis the linear polymer transported into a circular cavity hole is simulated. We have used the way of Monte Carlo approach in the presence of the applied external field to study polymer translocation into cavity hole using the 2D fluctuation bond model with single{segment Monte Carlo moves. While an external field is applied we analyze the translocation and concentrate on the translocation time into cavity hole as function of a polymer chain sizes. However there are other influences on forced translocation i.e the field strength,the width of cavity wall and the attractive interaction of the monomers and cavity hole, here we examined only the influence of the length of the chain N on the forced translocation time.The major effect of superimposed monomers number on polymer translocation has been proved. As our main result we found that a crossover scaling for translocation time τ with chain length τ ∼ N1+ν where ν is the Flory exponent.And the polymer escape time τ is directly proportional with the length of polymer N.
