    High Spatiotemporal Near‐Infrared II Fluorescence Lifetime Imaging for Quantitative Detection of Clinical Tumor Margins by Zhen Chen, Linjian Huang, Duyang Gao, Zhouzhou Bao, Dehong Hu, Wei Zheng, Jing Chen, Jiuling Liao, Hairong Zheng, Zonghai Sheng

    Published 2025-02-01
    “…While indocyanine green (ICG)‐based near‐infrared (NIR) fluorescence (FL) surgical navigation enhances the visual identification of tumor margins, its accuracy remains subjective, underscoring the need for quantitative approaches. In this study, a high spatiotemporal fluorescence lifetime (FLT) imaging technology is developed in the second near‐infrared window (NIR‐II, 1000–1700 nm) for quantitative tumor margin detection, utilizing folate receptor‐targeted ICG nanoprobes (FPH‐ICG). …”
