Abstract. Emission and absorption properties of indocyanine green (ICG) in Intralipid solution have been investigated. The study is focused on relatively low ICG concentration at a range of 0 to 20 μM. A diffusion model was used to analyze the emission properties of ICG solution at different concentrations.

ICG (Indocyanine green) is spectrally similar to iFluor 790, TF8WS (Tide Fluor 8WS), iFluor 800, and ICG Xtra-OSu. Our analyses of absorption and fluorescence spectra indicate that the peak absorbance of ICG associated with its monomeric form increases in the presence of … ICG were the presence of the absorption maximum, around. 800 nm, the conﬁnement to the vascular compartment. through binding with plasma proteins, the low toxicity (LD 50.

The enhanced NIR absorption of ICG-PDA-rGO allowed for effective photothermal nanoagent for PTT. As shown in Figure 3a, under the same concentration (200 μL of solution with 20 mg/L) and laser irradiation (808 nm, 0.6 W/cm 2, 5 min) conditions, the temperature of GO, PDA-rGO and ICG-PDA-rGO reached 33.7 o C, 40.2 o C and 54.4 o C, respectively. Indocyanine green (C 43 H 47 N 2 O 6 S 2 Na) is a water-soluble tricarbocyanine dye with a molecular weight of 775 daltons. 14, 15, 16 Initially used in cardiac and liver function tests, ICG’s clinical utility in fundus angiography results from its spectral properties in the near-infrared range. 3, 8 Compared with sodium fluorescein, whose peak absorption and emission is in the visible conjugation of ICG onto GS-Au25 led to a substantial blue shift of ICG absorption peak from 795 to 710 nm, which was due to the H coupling effect of multiple ICG molecules on the same Au25 sur-face (Fig. 2A) (25).

ICG absorption was measured on a microplate reader for calculation of ICG concentration in the LNs. The absorption spectrum of indocyanine green (ICG), a nontoxic dye used for medical diagnostics, depends upon its concentration as well as the nature of its environment, i.e., the solvent medium into which it is dissolved. In blood, ICG binds with plasma proteins, thus causing changes in its photoacoustic spectrum. We successfully encapsulated ICG in an ultrasound-triggerable perfluorocarbon ICG has somewhat bizarre light absorption behavior as a function of concentration because it tends to aggegrate in water at high concentrations. This means that the effective absorption does not increase linearly with increasing concentration. Absorption characteristics and stability of ICG bound to the retinal surface could be of relevance when investigating potential pathomechanisms of ICG related toxicity, which might be related not only to intraoperative but also to postoperative light exposure of patients after intravitreal use of IC … The absorption band of ICG diluted in the viscoelastic material was similar to the saline solution (BSS or BSS Plus)-diluted ICG. At lower concentrations of 0.001% or 0.00025%, the peak at 700 nm decreased, forming a shoulder in the curve, whereas the peak at 780 nm remained stable.

It has a peak spectral absorption close to 800 nm. These infrared frequencies penetrate retinal layers, allowing ICG angiography to image deeper patterns of circulation than fluorescein angiography. ICG binds tightly to plasma proteins and becomes confined to the vascular system. ICG has a half-life of 150 to 180 seconds and is ICG absorbs light over a broad wavelength range 650–840 nm in PBS, plasma, and ethanol S1A–S1C Fig. In PBS, ICG demonstrated absorption peaks at 710 nm (20 and 10µM) and 780 nm (20, 10, and 2µM).
