我们描述了荧光波动显微镜(FFM)的光学像差的影响,当通过一个单一的活细胞聚焦。FFM测量在荧光水溶液中进行,并证明是一个高度敏感的工具,以评估由细胞引入的光学像差。我们展示了一个自适应光学(AO)系统,以消除像差相关的偏见在FFM测量。我们的数据表明,AO不仅在组织深处成像时有用,而且在通过单个细胞层进行FFM测量时也有用。这项工作铺平了道路,FFM复杂的三维多细胞样品的应用。
We describe the effect of optical aberrations on fluorescence fluctuations microscopy (FFM), when focusing through a single living cell. FFM measurements are performed in an aqueous fluorescent solution and prove to be a highly sensitive tool to assess the optical aberrations introduced by the cell. We demonstrate an adaptive optics (AO) system to remove the aberration-related bias in the FFM measurements. Our data show that AO is not only useful when imaging deep in tissues but also when performing FFM measurements through a single cellular layer. This work paves the way for the application of FFM to complex three-dimensional multicellular samples.
