The ionic current during translocation. I0 and Ip are, respectively, the currents in the absence and presence of the particle.


Predict the ionic current resulting from the translocation of a cylindrical particle such as DNA through a nano-pore and infer information about the particle’s properties from the measurement of the ionic current
