Enzyme and template-directed synthesis of silica from non-organic silicon compounds, and amino silanes and silazanes and using

The present invention relates to a process for the synthesis of amorphous silica (Silicia, condensation products of silicic acid) and other polymeric metal (IV) compounds from non-organic silicon compounds or metal (IV) -compounds as well as amino silanes and silazanes, whereby (1) a template (collagen or another molecule that occurs (with ortho silicic acid or polymeric silicic acids and their salts or other metal IV) compounds in interaction) and (2) a silicase / carbonic anhydrase or a silicatein or related polypeptide is used for synthesis, and its technical Use.
