RT Journal Article T1 Nanoparticles for highly efficient multiphoton fluorescence bioimaging A1 Martínez Maestro, Laura A1 Martín Rodriguez, Emma A1 Vetrone, Fiorenzo A1 Naccache, Rafik A1 Loro Ramirez, Héctor A1 Jaque, Daniel A1 Capobianco, John A. A1 García Solé, José AB In this paper, we demonstrate for the first time that the new class of fluoride-based inorganic upconverting nanoparticles, NaYF4:Er3+, Yb3+, are the most efficient multiphoton excited fluorescent nanoparticles developed to date. The near-infrared-to-visible conversion efficiency of the aforementioned nanoparticles surpasses that of CdSe quantum dots and gold nanorods, which are the commercially available inorganic fluorescent nanoprobes presently used for multiphoton fluorescence bioimaging. The results presented here open new perspectives for the implementation of fluorescence tomography by multiphoton fluorescence imaging.
