Porous Materials to Support Bilayer Lipid Membranes for Ion Channel Biosensors
Figure 2
(a) Current recordings from a single experiment are shown for a PTFE filter preloaded with voltage-gated sodium channel (VGSC) liposomes. A BLM was formed on the PTFE filter and the control current level shown after 15 min at +80 mV. The current level is shown 15 min after addition of 100 μM veratridine (VTD) to both sides of the BLM, then 15 min after addition of 100 nM tetrodotoxin (TTX). (b) Corresponding histograms show the current amplitude distribution over the period of the recording.
