Compounds and methods are disclosed that are useful for noninvasive imaging in the near-infrared (NIR) spectral range. The NIR is highly sensitive for tumor detection and tracking. The application discloses targeting a tumor-enriched cell surface receptor with a ligand-conjugated fluorescent probe, which specifically allows detection of the tumor relative to the negligible animal autofluorescence.
本发明揭示了在近红外(NIR)光谱范围内进行非侵入性成像所使用的化合物和方法。 NIR对于肿瘤检测和跟踪非常敏感。本申请揭示了使用
配体结合的荧光探针靶向肿瘤富集的细胞表面受体,从而特异性地允许检测相对于动物自发荧光的可忽略的肿瘤。
