Polydim-I induced pores in anionic (AZO) bilayers according to the applied voltage (Vhold).

Mean (± SEM), minimum and maximum conductance of pores obtained in 3–6 different experiments for each Vhold condition. Dwell time (time duration of channel aperture) and Popen of pores (probability of pore aperture during a recording, calculated by the sum of time of all apertures under a Vhold divided by the total time of recording in that same Vhold condition) averaged after 3 experiments. Measurements of the single channels currents and duration of apertures were performed using PatchMaster software. Other analyses were performed in GraphPad Prism 5.0 software.
