In this issue, the 2014 Nobel Laureates in Chemistry discuss their work on single molecules, cells, and super-resolution optics (E. Betzig), nanoscopy with focused light (S. W. Hell) and single-molecule spectroscopy, imaging, and photocontrol (W. E. Moerner). In the same context, M. Orrit points out in his Editorial that single-molecule chemistry is more than superresolved fluorescence microscopy.

In the Communications section, W. Jiang et al. show how to track cancer metastasis in vivo by using a nanosensor (see picture). C. Martínez and K. Muñiz report an iodine-catalyzed Hofmann–Löffler reaction, and J. Greely et al. elucidate pathways for NO electroreduction on Pt(111) surfaces from first principles.
