Abstract
We investigated the transport of λ-DNA in 20 nm nanoslits under the influence of
applied AC and DC fields. At DC fields below 15 kV/m it was found that the addition
of 1 kHz AC fields with maximum strengths between 10 and 200 kV/m significantly
increased the mobility. At DC fields above 15 kV/m no influence of the AC
fields was observed. The observed behavior indicates that steric effects rather than
dielectrophoretic effects are responsible for the observed low DNA mobility in 20
nm nanoslits. The observed mobility behaviour can be explained if the DNA moves
by biased reptation in the nanoslits
