1. A fluid hose for conducting fluid, comprising:
an inner hose layer, wherein:
the inner hose layer encloses an interior of the fluid hose for receiving fluid,
the inner hose layer comprises an inner surface facing the interior of the fluid hose, and
the inner hose layer is formed from a plastic, wherein a surface-modifying substance is embedded within the plastic in a diffusion-resistant manner
wherein the surface-modifying substance is configured to change a surface property of the inner surface of the inner hose layer to prevent colonization of the inner surface by microorganisms, wherein the surface-modifying substance comprises a surface-polarizing substance configured to change a polarization of the inner surface of the inner hose layer, wherein the colonization of the inner surface by the microorganisms is prevented by the surface-polarizing substance, wherein the surface-polarizing substance comprises an organometallic compound that comprises a copper thiolate compound; and
an outer hose layer.
