Supplementary Information

This file contains Supplementary Figures 1-2 and Legends and Legends for Supplementary Movies 1 and 2. Supplementary Figure 1 presents the relative transport rates of a positive and negative dye through pnc-Si membranes functionalized with positive and negative surface chemistries. Supplementary Figure 2 presents evidence that the effective pore size of untreated pnc-Si may be reduced by a monolayer of adsorbed BSA.
