目前,荧光成像技术已成为生物医学应用中的重要工具之一,但其易受到光的穿透能力有限、组织自体荧光干扰等因素的影响。与可见光和近红外一区(NIR⁃Ⅰ)光相比,近红外二区(NIR⁃Ⅱ) 荧光成像具有更深的穿透深度、更高的成像分辨率和灵敏度、更低的背景噪音和更高的信噪比,因此在脑血管成像和重大脑疾病的成像诊断方面展现出潜在的应用前景。本文主要介绍了不同类型NIR⁃Ⅱ荧光探针及优化其光学性能的策略。同时,总结了这些探针在脑成像方面的研究进展,并对未来临床应用所面临的问题进行了探讨。
At present, fluorescence imaging has become one of the important tools in biomedical applications, but it is very susceptible to the limited penetration of light and auto-fluorescence in tissues. Compared with the fluorescence imaging in visible region and the first near-infrared window(NIR-Ⅰ), the second near-infrared(NIR-Ⅱ) fluorescence imaging show the deeper penetration depth, lower background noise, higher imaging resolution, sensitivity, and signal-to-noise ratio, thus demonstrating the promising applications in cerebrovascular imaging and diagnosis of major brain diseases. Based on this, we mainly focus on the construction of different NIR-Ⅱ fluorescent probes and several strategies to optimize their optical performance. Meanwhile, the recent progress of these probes in brain imaging is summarized and some issues facing the future clinical applications are discussed.
