摘要： A method for the self-assembled production of a topographically surface structured cellulose element. First, a mold is provided having on one side a first surface which is in a complementary manner topographically structured and which is permeable to oxygen. Next, a liquid growth medium containing cellulose producing bacteria is provided. Then, the mold is placed to form a interface such that the side of the mold with the first surface is in direct contact with the liquid growth medium, and an opposite side is facing air or a specifically provided oxygen containing gas surrounding. This allows bacteria to be produced and deposit cellulose on the first surface and developing on the interface a surface structured surface complementary thereto, until a cellulose layer with a thickness of the element of at least 0.3 mm is formed. Finally; the element is removed from the mold.
