Abstract Control over marine biofouling on artificial surfaces has been of interest because undesired fouling of marine organisms onto marine vessels and equipments leads to disturbance of marine ecosystem and increase of fuel consumption. Much effort has been made to find methods for marine antifouling coatings. Dextran, which is one of natural polysaccharides, has been known as effective antifouling materials. For example, mammalian cell- and bacteria-repellent property of dextran-coated substrates were previously reported. However, marine antifouling property of dextran-coated substrates has not been fully investigated, yet. In this study, we demonstrate a method to suppress marine fouling using the dextran coating. Dextran was conjugated with catechol, and the resulting material was used for surface coating of solid substrates. The marine antifouling property of the surface was confirmed using marine diatom adhesion assays, which revealed that the dextran coating reduced diatom adhesion.
