Figure 5. Detection of host-guest interactions by an α-HL nanopore.
(a) The raw data for the presence of SC4:V2+-trans-Az in the trans compartment without (top) and with (bottom) the addition of 1.6 μM SC4 at −140 mV. (b) τon carried out in the presence of SC4:V2+-trans-Az, SC4:V2+-trans-Az with additional 1.6 μM SC4 (SC4:V2+-trans-Az + SC4) and SC4, respectively. (c) The number of blockages versus the probing time for 8.0 μM SC4 (blue), SC4:V2+-trans-Az after UV irradiation (black) and SC4:V2+-trans-Az (red) at the potential of −100 mV.
