Antiadhesive activity of ulvan polysaccharides covalently immobilized onto titanium surface

- We modified titanium surfaces by ulvans polysaccharide.
- We characterized modifications by XPS, AFM and contact angle.
- Ulvans on titanium surface strongly decreased by about 90% the adhesion of Pseudomonas aeruginosa.
- Polysaccharide also inhibited the bacterial spreading on the surface.
