Light in the near-infrared (NIR) region between 700-900 nm can penetrate deep into living tissue, thereby offering a unique opportunity to use near-infrared fluorescence (NIRF) imaging techniques to detect and visualize fluorescent probes in-vivo. In the past few years, many...

This article describes the design and preparation of a novel fluorescence resonance energy transfer (FRET)-based ratiometric sensor with the polymer nanoparticle as scaffold for detecting Hg(2+) in aqueous media. In this study, a fluorescent dye fluorescein isothiocyanate (FITC, served as...

Angewandte Chemie (International ed. in English), 51(31), 7634-7636 (2012-06-08)
Probes to dye for: Rhodamine-inspired Si-pyronine, Si-rhodamine, Te-rhodamine, and Changsha NIR dyes have been developed recently. These dyes show fluorescence in the far-red to near-infrared region, while retaining the advantages of the original rhodamines, such as high fluorescence quantum yield...

Molecular imaging, 8(6), 341-354 (2009-12-17)
Fluorophores are potentially useful for in vivo cancer diagnosis. Using relatively inexpensive and portable equipment, optical imaging with fluorophores permits real-time detection of cancer. However, fluorophores can be toxic and must be investigated before they can be administered safely to...

Biomaterials, 33(33), 8569-8578 (2012-08-22)
Polymeric nanoparticles have been widely applied to oral delivery of protein drugs, however, few studies focused on the systematical elucidation of the size-dependent oral absorption mechanism with well-defined polymeric nanoparticles. Rhodamine B labeled carboxylated chitosan grafted nanoparticles (RhB-CCNP) with different...

Current opinion in biotechnology, 18(1), 17-25 (2007-01-20)
In vivo fluorescence imaging uses a sensitive camera to detect fluorescence emission from fluorophores in whole-body living small animals. To overcome the photon attenuation in living tissue, fluorophores with long emission at the near-infrared (NIR) region are generally preferred, including...
