Estimation of the Diffusion Coefficients of Small Molecules by Diffusion Measurements with Agar-gel and Theoretical Molecular Modeling

Diffusion is a spontaneous process and one of the physicochemical phenomena responsible for molecular transport, the rate of which is governed mainly by the diffusion coefficient; however, few coefficients are available for small molecules. We have constructed a simple and convenient experimental system with agar-gel to measure the diffusion coefficients of sugars.
