Partial oxidation of macroporous silicon membranes with different pore wall thicknesses results in a regular compartmentalized structure of SiO 2 domains separated by opaque silicon, as shown on the cover. Dertinger and co‐workers report on p. 3135 that control of the experimental conditions ensures the flatness of the partially oxidized macroporous silicon. Fluorescence crossover is minimized within the photonic crystal, enabling its use as a microarray support for sensitive bioanalytic applications, such as DNA hybridization.
