Properties and Photophysical Data: Indocyanine green is a NIR fluorescent dye operating in the 700-900 nm wavelength range. It binds to β-lipoproteins, particularly albumin, in plasma and exhibits fluorescence emission in the shortwave infrared window (SWIR; 1,000-2,000 nm) which enables in vivo imaging, including intravital microscopy, non-invasive real-time imaging in blood and lymph vessels, and imaging of hepatobiliary clearance. Imaging of indocyanine green in SWIR shows increased sensitivity, contrast, and resolution of fine anatomical structures over NIR. Excitation and emission maxima (λ) are 787 nm and 815 nm, respectively; quantum yield = 0.14; extinction coefficient = 223,000 M-1cm-1; A280 correction factor = 0.07.
