Abstract: | Polymer translocation through the nanochannel is studied by means of a Monte Carlo approach, in the presence of a static or
oscillating external electric voltage. The polymer is described as a chain molecule according to the two-dimensional “bond
fluctuation model”. It moves through a piecewise linear channel, which mimics a nanopore in a biological membrane. The monomers
of the chain interact with the walls of the channel, modelled as a reflecting barrier. We analyze the polymer dynamics, concentrating
on the translocation time through the channel, when an external electric field is applied. By introducing a source of coloured
noise, we analyze the effect of correlated random fluctuations on the polymer translocation dynamics. |
