proposed is totally innocuous to components if the bio lm is
prevented. The prevention of bio lms consist in reducing the
penetration time, avoiding irreversible cell adhesion and produc-
tion of exopolymeric substances that “glue” the cells to the surface.
Furthermore, at the end of the test and visualization of the defect,
the tested materials may be sterilised to guarantee that they are
cell free. Depending on the type of material, sterilization may be
achieved by heat, UV light, addition of chemical compounds or
simple desiccation.
