electronic contribution to image fue nonfluorescent metal oxides particles, even for particles smaller than the diffraction limit of an optical microscope with good signal to noise ratio. We have applied CARS microscopy in imaging these metal oxides nanoparticles (ZnO, TiOz and FeZO3) in alveolar macrophage cells in vitro.

Fluorescent Nanorods and Nanospheres for Real-Time In Viv o

nanoparticles (Supporting Information, Figure S1) allowed for real-time multiplexed in vivo imaging with multiphoton microscopy within the same tumor. Applying this technology, we measured transport in vitro and in vivo for a pair of nanospheres and nanorods with equal hydrodynamic size.

Potentials and pitfalls of fluorescent quantum dots for

Multiphoton microscopy: a process in which more than one photon, each with a fraction of the energy needed to excite fluorescent molecules, is simul-taneously absorbed by the fluorophore, resulting in fluoresce emission. This process facilitates the use of infrared light (which, owing to its longer


microscopy (MPM) has been successfully used as a noninvasive in vivo deep-tissue imaging tool ( 20 24 ). Here, motivated by previous works ( 14 , 19 , 24 , 25 ), biocompatible
