Based on the configuration changes induced by some special interactions between polymer chains, the translocation of a single polymer chain through nanopore on a membrane was investigated. The influence of the interactions between the introduced polymer chain and the translocating one on the. mean first-passage time MFPT) was studied, and then the corresponding numerical simulations were presented under different conditions. It is shown that, the interactions between polymer chains have influence on the mean first-passage time MFPT) and the translocating polymer chain can significantly decrease under certain conditions. Moreover, some relevant factors associated with the translocating process such as the effects of the values of chemical potential are also discussed.
