For the application of polysaccharides in medical materials and drug delivery systems, technologies that can modulate their properties in aqueous environments without damaging their molecular backbone are essential. In this study, we investigated the effects of plasma treatment on the interactions between polysaccharides and water and on the molecular mobility of dextran, a neutral polysaccharide, in aqueous solution. The results showed that, although no clear changes were observed in the polysaccharide backbone, chemical exchange between the OH groups and water was promoted, and the diffusion coefficient increased by up to approximately 10%. This approach is expected to provide a novel strategy for functionalizing polysaccharides while preserving their intrinsic molecular structure.
