On p. 1351 , Geoffrey Ozin and co‐workers report on a novel artificial nose system dubbed the photonic nose, which is based on a simple and cost‐effective pixelated array of surface‐functionalized nanoporous Bragg mirrors that enable discrimination of different vapor phase analytes, exemplified by alkanes and alcohols as well as molecules comprising the headspace of different bacteria, detected and analyzed by diagnostic changes in red, green and blue color levels recorded by a digital camera.
