Abbreviations: polytetrafluoroethylene (PTFE), polycarbonate track-etched (PCTE), polycarbonate track-etched gold-coated (PCTEG), porous silicon (PSi), microslit silicon nitride gold-coated (MSSN-Au).
One-liter timed passage data are reported as mean ± standard deviation (n = 3). Absolute flow rate data are reported as mean passage time / 1,000 ± coefficient of variation, and those values were further divided by membrane surface area to calculate surface area-normalized flow rates.
