The physical principle.
Hydrophobic interaction is a basic physical principle: hydrophobic (water-repellent) particles accumulate in an aqueous environment and are held together by the forces of the surrounding water molecules.

  Hydrophobic properties.
Bacteria have certain hydrophobic cell surface structures. These are needed, for example, to adhere to host (wound) tissue in the initial phase of a wound infection. Cutimed Sorbact, on the other hand, is coated with a fatty acid derivative (DACC) which gives the dressing its strongly hydrophobic properties.

  The Sorbact method.
Wound bacteria are irreversibly bound to the dressing when they come into contact with the hydrophobic dressing fibres in the moist wound environment.
