In this review paper, we summarize the significant advancements in the field of fluorescence lifetime imaging microscopy (FLIM), particularly wide-field FLIM with single-molecule sensitivity, achieved using the time-correlated single-photon counting-based position-sensitive LINCam system. Fluorescence lifetime adds valuable information beyond conventional intensity-based imaging, enabling diverse applications across research fields. Here, we focus on three primary bioimaging applications: (I) single-molecule FLIM in the far-red spectral region, (II) fast and multiplexed super-resolution imaging of cells, and (III) three-dimensional super-resolution imaging with high axial localization precision. Recent advances in position-sensitive detector technologies offer exciting opportunities for high-throughput super-resolution imaging with enhanced localization precision.
在这篇综述论文中,我们总结了荧光寿命成像显微镜(FLIM)领域的重大进展,特别是利用基于时间相关单光子计数的位置敏感型LINCam系统实现的具有单分子灵敏度的宽场FLIM。荧光寿命除了能提供超越传统强度成像的有价值信息外,还能在各个研究领域实现多种应用。在此,我们重点关注三个主要的生物成像应用:(I)远红光光谱区域的单分子FLIM,(II)细胞的快速和多路复用超分辨率成像,以及(III)具有高轴向定位精度的三维超分辨率成像。位置敏感探测器技术的最新进展为具有更高定位精度的高通量超分辨率成像提供了令人兴奋的机会。
