Change in the cellular structure during hydration and dehydration is a crucial factor for the successful cryopreservation. In this study, the swelling process of polymer gel beads, used as models of biological cells, was followed in the aqueous sugar solutions by the measurement of nuclear magnetic relaxation times. It was found that the swelling was retarded in the presence of sucrose molecules, and the preferential water absorption by the gel beads was indicated.
