摘要

三维超分辨率荧光显微镜通常需要复杂的设置、样品制备或长时间测量。但 SOFI 是一个显著的例外,它只需要记录一连串的帧,不需要对硬件进行任何修改,但作为一种宽视场方法,它在厚而密集的样品中面临着问题。我们将 SOFI 与时间聚焦双光子激发相结合,这种宽场方法能够激发三维体积中的薄片。只要能进入显微镜的激发路径,时间聚焦法就很容易实现。SOFI 的实施也很简单。通过合并这两种方法,我们获得了量子点染色神经元的超分辨三维图像。我们的方法减少了焦外荧光探针的漂白现象,提高了信噪比,可用于在厚而密集的样本中提高分辨率。

3D super-resolution optical fluctuation imaging with temporal focusing two-photon excitation.

3D super-resolution fluorescence microscopy typically requires sophisticated setups, sample preparation, or long measurements. A notable exception, SOFI, only requires recording a sequence of frames and no hardware modifications whatsoever but being a wide-field method, it faces problems in thick, dense samples. We combine SOFI with temporal focusing two-photon excitation - the wide-field method that is capable of exciting a thin slice in 3D volume. Temporal focusing is simple to implement whenever the excitation path of the microscope can be accessed. The implementation of SOFI is straightforward. By merging these two methods, we obtain super-resolved 3D images of neurons stained with quantum dots. Our approach offers reduced bleaching of out-of-focus fluorescent probes and an improved signal-to-background ratio that can be used when robust resolution improvement is required in thick, dense samples.
