Abstract
A surface on a polymeric film having an array of patterned structures, wherein the array of patterned structures influences fluid flow of the surface and causes reduced attachment of a biological material.
Claims21
A polymeric film, comprising:
- a surface,
- wherein the surface of the polymeric film comprises an array of patterned structures,
- wherein topographies of the array of patterned structures are selected and arranged so that when the surface of the polymeric film is rinsed and/or dipped in a fluid, the array of patterned structures induces a turbulent fluid flow and removes biological material thereon, and
- wherein when a predetermined space or a predetermined width of the topographies of the polymeric film is larger than a diameter or dimension of the biological material, the rinsed and/or dipped surface of the polymeric film is characterized such that it exhibits a reduced attachment of the biological material.
