Diffusion coefficients of glucose and ethanol in cell‐free and cell‐occupied calcium alginate membranes

TL;DR: The diffusivities of glucose and ethanol in cell‐free and cell‐occupied membranes of calcium alginate were measured and agreed closely with the inverse ratio of the hydrodynamic raii for the two molecules in water, indicating that thehydrodynamic theory of diffusion in liquids may be applicable to diffusion in dilute alginates gels.
