Indocyanine green (ICG) is a well-known fluorescent dye approved for clinical applications, which has a short circulation time in the vascular system and low photostability. At high temperatures the molecular solution of the photosensitizer self-assembles into a stable J-aggregate form of ICG nanoparticles (ICG NPs) with the absorption peak in the near-infrared range. Investigation of ICG NP stability in human blood and plasma using a fiber-spectroscopic system demonstrates no difference in absorption properties and different dependence of the integrated fluorescence ratio between ICG monomers and J-aggregates in blood and plasma. Transition of ICG NP aggregates to the monomeric form in human blood plasma results in a higher circulation time of the fluorescent dye in the vascular system. High stability of aggregates and a low elimination rate may increase efficiency of fluorescent diagnostics of near-tumor tissues.
