Table 1 Values for the capture rate (r 0) of P. aeruginosa (P.a.) and E. coli (E.c.) cells by the α-HL nanopore in the absence of the applied voltage, and the effective electric valence (quantified by z, see text) on the bacterial surface in contact with the α-HL’s lumen opening, estimated in the absence and presence of trans-added CMA3 peptide (20 μM) from the exponential fits shown in Fig. 4
