(Introduction) The various biological phenomena are concern with diffusion. We study about the visualization of glucose diffusion in the cellulose membrane, and make the fittest model to this diffusion phenomenon. (Result) It was possible for the glucose molecule to visualize by ammoniacal silver nitrate solution which was diffused into the cellulose membrane previously. We measured the diffusion distance by the silver density by image analysis. This experimental data seemed to be ogistic behaviour. Then we tried to be fit logistic model by curve fit. In this way, we got the diffusion coefficient D by calculating. This D of glucose molecule in cellulose membrane is approximately D=1.04x10-6[cm2/s]. Then, this value is 6 times as much as that of in the solution. (Conclusion) We visualized the glucose diffusion and measured the diffusion coefficient. This was the support layer of coacervate cellulose membrane had 6 times larger than the diffusion constant in solution.
