The cover picture shows an etched and metallized optical fiber tip for chemical analysis on the nanometer scale using near-field optical microscopy and spectroscopy. The background shows an image of nanospheres embedded in a polymer matrix that were visualized via fluorescence. Further details are given in the review by R. Zenobi and V. Deckert on pages 1746–1756.
