摘要

Near-infrared (NIR) fluorescence imaging in the second near-infrared region (NIR-Ⅱ,1000-1700 nm) is an important and attractive imaging method for biomedical research and clinical applications,and can achieve high spatial resolution,high signal-to-background ratio (SBR) and deeper tissue imaging owing to nearly zero auto-fluorescence background and tissue scattering [1,2].Smaller optical sub-window such as NIR-IIb (1500-1700 nm) has provided significant improvements in in vivo fluorescence imaging clarity and penetration depth.
