(a) Dwell times for λ-DNA translocations through plasmonic nanopores upon plasmon excitation at different powers (longitudinal) in 1 M KCl (blue circles, left axis) and in 2 M LiCl (red diamonds, right axis). (b) Dwell times at different temperatures for λ-DNA translocations through 10 nm in diameter conventional nanopores in 1 M KCl (blue circles, left axis) and in 2 M LiCl (red diamonds, right axis). All error bars were calculated as the standard error of the mean (and are smaller than the symbols for 1 M KCl in (a)).
