Process for the self-assembled production of a topographically structured cellulose element on the surface (10), in which, in a first step, a mold (2) is provided, with a first surface (4) on one side that is topographically structured on the surface, in a complementary manner, and which is permeable to oxygen, in which a liquid growth medium containing cellulose-producing bacteria is provided, and in which the mold (2) is placed to form a liquid/air interface of the liquid growth medium, such that the face of the mold with the first surface (4) is in direct contact with the liquid growth medium, and with an opposite face (3) that is oriented towards the surrounding air or gas containing oxygen specifically provided, allowing said bacteria to produce and deposit cellulose on said first surface (4) and develop at the interface therewith a topographically structured surface e on the surface complementary to it, until a contiguous cellulose layer is formed with a thickness of the element (10) of at least 0.3 mm, and in which, in a second stage, the element (10 ) is extracted from said mould. |
