FD-1080 is a fluorophore with both excitation and emission in the NIR-II region (Ex=1064 nm, Em=1080 nm). FD-1080 can be used for in vivo imaging[1].
FD-1080 shows superior photostability under the continuous laser irradiation. The quantum yield of FD-1080 is 0.31%, and can be increased to 5.94% after combining with fetal bovine serum (FBS) to form FD-1080-FBS complexes[1].
The 1064 nm NIR-II excitation of FD-1080 is demonstrated with the high tissue penetration depth and superior imaging resolution compared to NIR excitation from 650 nm to 980 nm. Deeptissue and high-resolution in vivo imaging for the left hindlimb vasculature, abdomen, and brain vessels was realized, allowing penetration through intact skin, tissue, and skull. FD-1080 also quantifying the respiratory rate based on the dynamic imaging of respiratory craniocaudal motion of the liver for the awake and anaesthetized mouse[1].

An Efficient 1064 nm NIR-II Excitation Fluorescent Molecular Dye for Deep-Tissue High-Resolution Dynamic Bioimaging
Angew Chem Int Ed Engl 2018 Jun 18;57(25):7483-7487.PMID:29493057DOI:10.1002/anie.201801226.
A small-molecule fluorophore FD-1080 with both excitation and emission in the NIR-II region has been successfully synthesized for in vivo imaging. A heptamethine structure is designed to shift the absorption and emission into NIR-II region. Sulphonic and cyclohexene groups are introduced to enhance its water solubility and stability. The quantum yield of FD-1080 is 0.31 %, and can be increased to 5.94 % after combining with fetal bovine serum (FBS). Significantly, 1064 nm NIR-II excitation was demonstrated with the high tissue penetration depth and superior imaging resolution compared to previously reported NIR excitation from 650 nm to 980 nm. FD-1080 is not only capable of realizing non-invasive high-resolution deep-tissue hindlimb vasculature and brain vessel bioimaging, but also quantifying the respiratory rate based on the dynamic imaging of respiratory craniocaudal motion of the liver for the awake and anaesthetized mouse.
J-Aggregates of Cyanine Dye for NIR-II in Vivo Dynamic Vascular Imaging beyond 1500 nm
J Am Chem Soc 2019 Dec 11;141(49):19221-19225.PMID:31746598DOI:10.1021/jacs.9b10043.
Light in the second near-infrared window, especially beyond 1500 nm, shows enhanced tissue transparency for high-resolution in vivo optical bioimaging due to decreased tissue scattering, absorption, and autofluorescence. Despite some inorganic luminescent nanoparticles have been developed to improve the bioimaging around 1500 nm, it is still a great challenge to synthesize organic molecules with the absorption and emission toward this region. Here, we present J-aggregates with 1360 nm absorption and 1370 nm emission formed by self-assembly of amphiphilic cyanine dye FD-1080 and 1,2-dimyristoyl-sn-glycero-3-phosphocholine. Molecular dynamics simulations were further employed to illustrate the self-assembly process. Superior spatial resolution and high signal-to-background ratio of J-aggregates were demonstrated for noninvasive brain and hindlimb vasculature bioimaging beyond 1500 nm. The efficacy evaluation of the clinically used hypotensor is successfully achieved by high-resolution in vivo dynamic vascular imaging with J-aggregates.
