Micropatterns of silica were generated under biocompatible conditions by a combination of microcontact printing (μCP), layer‐by‐layer (LbL) self‐assembly, and biomimetic silicification. Quaternary amine‐containing poly(diallyl dimethyl ammonium chloride) induced polycondensation of silicic acid, resulting in spatioselective formation of silica micropatterns. Scale bar: 10 μm.
