摘要: We measure current blockade and time distributions for single-stranded DNA polymers during voltage-driven translocations through a single alpha-hemolysin pore. use these data to determine the velocity of in Our measurements imply that, while longer than pore are translocated at constant speed, shorter increases with decreasing length. This is nonlinear applied field. Based on this data, we estimate effective diffusion coefficient energy penalty extending molecule into
