Extended Data Figure 2: Length distributions of CNT porins measured from TEM images.
From: Stochastic transport through carbon nanotubes in lipid bilayers and live cell membranes

a, CNT porin sample after cutting and purification procedures (n = 65). b, Cut and purified sample after passing through a 100 nm pore filter membrane (n = 36). c, As b but after passing through a 50 nm pore filter membrane (n = 156). µ indicates the mean CNT porin length.
