Monte Carlo Simulation Study Of Translocation Of A Polymer Out Of A Circular Cavity

Abstract

In this study we have investigated the static and dynamic properties of linear polymer with different chain length translocated out of circular cavity using Monte Carlo simulation. We used the bond fluctuation method (BFM) with metropolis algorithm to study the translocation process of a linear polymer chain of length N in two dimensions (square) lattice. To overcome entropic barrier, we placed the middle monomers in the middle of pore of cavity. We found that the scaling relation of mean square end-to-end distance and mean square radius of gyration of flexible chain polymer as function of chain length N are in good agreement with Flory exponent for narrower pore of cavity. In addition to these, our study result showed that both cavity radius and pore width affect the scaling behavior of escape time. Moreover, the average escape time has direct relationships with chain length and it has inverse relationships with pore width.
