Near-Infrared Fluorescent Dyes
Near-infrared (near-IR, NIR) dyes offer important advantages over traditional visible light dyes. Because cellular or tissue components produce minimal autofluorescence in the near-IR region, near-IR dyes have the potential to offer highly specific and sensitive detection in complex biological systems. Also, because light with wavelength in the near-IR region has strong tissue penetration, near...
متن کاملNear-infrared fluorescent probes: synthesis and spectroscopic investigations of a few amphiphilic squaraine dyes.
With the objective of developing near-infrared fluorescence probes for biological applications, a few squaraine dyes 3a-d, containing amphiphilic substituents, were synthesized and their photophysical properties have been investigated in the presence and absence of the organized media. These dyes exhibited absorption in the range 630-650 nm, with significant absorption coefficients (epsilon = 1...
متن کاملSynthesis and applications of Rhodamine derivatives as fluorescent probes.
Rhodamine dyes are widely used as fluorescent probes owing to their high absorption coefficient and broad fluorescence in the visible region of electromagnetic spectrum, high fluorescence quantum yield and photostability. A great interest in the development of new synthetic procedures for preparation of Rhodamine derivatives has arisen in recent years because for most applications the probe mus...
متن کاملA unique approach toward near-infrared fluorescent probes for bioimaging with remarkably enhanced contrast
Near-infrared (NIR) fluorescent probes are attractive molecular tools for bioimaging because of their low autofluorescence interference, deep tissue penetration, and minimal damage to sample. However, most previously reported NIR probes exhibit small Stokes shift, typically less than 30 nm, and low fluorescence quantum yield, strictly limited contrast and spatial resolution for bioimaging. Here...
متن کاملNovel Tumor Targeting Near Infrared Fluorescent Probes
Advances within the field of in vivo optical imaging have added an arsenal of powerful tools for monitoring tumor development non-invasively in preclinical cancer models (Contag et al., 1997). Bioluminescence allows both, sensitive and rapid analysis of light emitted from luciferase-labeled cells and can be used to measure tumor burden from otherwise non-visible deep tissue locations when calip...
