| Summary: | Deep-seated tumors present significant diagnostic challenges and pose substantial mortality risks due to their occult anatomical localization. Current diagnostic paradigms predominantly depend on conventional imaging modalities; nevertheless, inherent technical constraints persistently compromise diagnostic precision and therapeutic efficacy. In contrast to traditional methodologies, near-infrared (NIR; 700–1700 nm) fluorescence imaging (FLI) demonstrates superior sensitivity and spatiotemporal resolution, facilitating real-time intraoperative visualization and precision-guided surgical interventions. This paper explores fluorescence materials with tailored structures for tumors at different depths. We critically analyze optimization strategies for NIR fluorescence materials while evaluating their comparative advantages in stratified tissue imaging. This study presents a systematic evaluation of NIR fluorescence molecular tomography (FMT) systems and image reconstruction methodologies. These insights provide feasible ideas for detecting and treating tumors at varying depths in clinical practice. Furthermore, the application of NIR fluorescent materials in tumor diagnosis, navigation-guided surgery, and phototherapy (including photothermal, photodynamic, and immunomodulation therapies) is discussed. Finally, the prospects and challenges of clinical transformation are summarized. |
