荧光光片显微镜在发育生物学中得到了迅速的应用。由于辐射水平远低于共焦显微镜和多光子显微镜,它能够在发育过程中对完整的器官和生物体进行长时间的研究。通过用与检测轴垂直的第二物镜选择性地照亮焦平面来实现最小样本曝光。光片显微镜能够在生物样本生长时研究完整的生物样本,这突显了更深入地对生物样本成像的重要性。然而,深层组织显微镜受到自体荧光和光散射的阻碍。因此,直接观测仅限于高度透明和薄的样品。在这里,我们展示了如何依靠可逆光开关荧光来有效地消除自发荧光,同时我们提出了一种未来研究和控制光在光学厚度组织中传播的方法。
Fluorescence light-sheet microscopy is gaining rapid adoption in developmental biology. With irradiation levels well below that of confocal and multi-photon microscopy, it enables the study of intact organs and organisms for prolonged time periods during development. Minimal sample exposure is achieved by selectively illuminating the focal plane with a second objective orthogonal to the detection axis. The light-sheet microscope’s ability to study intact biological samples as and when they grow highlights the importance of imaging deeper into biological samples. Yet, deep-tissue microscopy is hampered by autofluorescence and the scattering of light. Direct observations are therefore limited to highly transparent and thin samples. Here, we show how autofluorescence can be eliminated effectively by relying on reversible photoswitching fluorescence while we propose a way forward to study and control light propagation in optically-thick tissues.
