A nanoparticle-supported fluorescence resonance energy transfer system formed via layer-by-layer approach as a ratiometric sensor for mercury ions in water.

Chao Ma et al.

Analytica chimica acta, 734, 69-78 (2012-06-19)

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

Toxicity of organic fluorophores used in molecular imaging: literature review.

Raphael Alford et al.

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

Near-infrared fluorescent probes for imaging vascular pathophysiology.

Jan Klohs et al.

Basic research in cardiology, 103(2), 144-151 (2008-03-08)

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

Rhodamine-inspired far-red to near-infrared dyes and their application as fluorescence probes.

Yuan-Qiang Sun et al.

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

Size-dependent absorption mechanism of polymeric nanoparticles for oral delivery of protein drugs.

Chunbai He et al.

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

Fluorescence imaging in vivo: recent advances.

Jianghong Rao et al.

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
