49_20b/2010Inside Cover: Bright Three-Photon Luminescence from Gold/Silver Alloyed Nanostructures for Bioimaging with Negligible Photothermal Toxicity (Angew. Chem. Int. Ed. 20/2010)

Au/Ag alloyed nanostructures exhibit a bright three-photon luminescence upon excitation by a femtosecond laser, and have an intensity level one order of magnitude higher than pure Au or Ag nanoparticles. As Y. Xia, J.-X. Cheng, and co-workers describe in their Communication on page 3485 ff., the excitation is outside the range of plasmon resonance, thus enabling bioimaging with negligible photothermal toxicity.
