The design of dual‐mode fluorescence and Raman tags stimulates a growing interest in biomedical imaging and sensing applications as they offer the possibility to synergistically combine the versatility and velocity of fluorescence imaging with the specificity of Raman spectroscopy. Although lanthanide‐doped fluoride nanoparticles (NPs) are among the most studied fluorescent nanoprobes, their use for...
Arylazo sulfonates (Ar−N=N−SO3Na) have been found to undergo photografting on gold surface through both Au−Nsp2− and Au−Csp2− bond formation. The functionalized materials have been fully characterized by infrared reflection absorption spectroscopy (IRRAS), Raman, XPS, DFT calculations and UV‐Vis absorption spectroscopy. These methods permit to evidence aromatic substituents (IRRAS), the Au−N=N signature...
