Near-infrared narrow-band imaging of gold/silica nanoshells in tumors.
Gold nanoshells (GNS) are a new class of nanoparticles that can be optically tuned to scatter or absorb light from the near-ultraviolet to near-infrared (NIR) region by varying the core (dielectric silica)/shell (gold) ratio. In addition to spectral tunability, GNS are inert and bioconjugatable, making them potential labels for in vivo imaging and therapy of tumors. We report the use of GNS as ...
متن کاملNarrow-band single-photon emission in the near infrared for quantum key distribution.
We present a detailed study of photophysical properties of single color centers in natural diamond samples emitting in the near infrared under optical excitation. Photoluminescence of these single emitters has several striking features, including narrow-band (FWHM 2 nm) fully polarized emission around 780 nm, a short excited-state lifetime of about 2 ns, and perfect photostability at room tempe...
متن کاملNarrow-Band Biphoton Generation near Atomic Resonance
Generating nonclassical light offers a benchmark tool for the fundamental research and potential applications in quantum optics. Conventionally, it has become a standard technique to produce the nonclassical light through the nonlinear optical processes occurring in nonlinear crystals. In this review we describe using cold atomic-gas media to generate such nonclassical light, especially focusin...
متن کاملNarrow band imaging cholangioscopy in hilar cholangiocarcinoma.
Per oral cholangioscopy has been developed as a diagnostic modality for evaluation of bile duct lesions. Per oral cholangioscope with narrow band imaging (NBI) system can provide good quality images of bile duct lesions. There is limited data on per oral cholangioscopy using NBI in biliary tract diseases. We report our experience of NBI cholangioscopy in hilar strictures.
متن کاملNear-infrared narrow-band photometry of M–giant and Mira stars: models meet observations
From near-infrared, narrow-band photometry of 256 oxygen-rich Mira variables we obtain evidence about the loops that these stars follow in colour–colour diagrams.We also find a phase lag between indices related to molecular band-strength of titanium oxide and vanadium oxide. We compute colours for normal M–giants and Miras using hydrostatic and hydrodynamic model atmospheres and very extensive ...
