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.
