Figure 2

Permeability coefficient ratios of permeant vs. permeant MW. Symbols: experimental permeability coefficient ratios of TEA to SA, TEA to BSA, TEA to PSS, TEA to BEV, and TEA to DEXs with MW 4 and 20 kDa (DEX 4k and DEX 20k). The lines represent the theoretical calculations of the permeant permeability ratio vs. permeant MW at different effective membrane pore radius using Eqs. 4–6.
