(a) Mechanical stability in the DW and PDW chips as determined with a mechanical vibrator. The survival rate was defined as the number of stable BLMs/16-ch for 30 s (n = 4, mean ± S.D.). (b) Comparison of the power density spectra of αHL open-channel currents between the DW and PDW chips. The PDW chip showed significantly reduced noise in the lipid bilayer. (c) The long-term stability of BLMs in the PDW chip. Channel opening events are presented as a function of days. The channel signals of alamethicin were observed for 14 days.
