The reactive conversion of biosilica meso‐ and nanostrucures into new compositions with retention of shape and fine features is demonstrated. The shape‐preserving nature of the chemical conversion process is illustrated for the reaction of silica‐based diatom frustules with Mg gas to form MgO (see Figure). This technique is promising for the mass production of a variety of low‐cost genetically engineered meso‐ and nanodevices.
