摘要：
瞬态吸收（TA）光谱学已被证明对我们理解生物系统中的能量和电荷转移至关重要，能够在亚皮秒时间尺度上测量光活性蛋白。近年来，超快TA光谱学已被应用于在体研究，为活体光合微生物内的光合捕光和电子转移过程提供亚皮秒级测量。然而，由于活细胞内不同光活性色素数量众多，且相关光活性反应方案复杂，所得数据的分析受到阻碍。在此，我们展示了如何将在体超快TA光谱学应用于生命之树中多种多样的生物，包括光合生物和非光合生物。我们开发了一系列软件工具，用于对在体TA数据集执行全局分析、寿命分析和目标分析。这些进展确立了在体TA光谱学作为研究生命系统中能量和电荷转移的一种多功能技术。
英文摘要：
Transient absorption (TA) spectroscopy has proved fundamental to our understanding of energy and charge transfer in biological systems, allowing measurements of photoactive proteins on sub-picosecond timescales. Recently, ultrafast TA spectroscopy has been applied in vivo, providing sub-picosecond measurements of photosynthetic light harvesting and electron transfer processes within living photosynthetic microorganisms. The analysis of the resultant data is hindered by the number of different photoactive pigments and the associated complexity of photoactive reaction schemes within living cells. Here we show how in vivo ultrafast TA spectroscopy can be applied to a diverse array of organisms from the tree of life, both photosynthetic and non-photosynthetic. We have developed a series of software tools for performing global, lifetime and target analysis of in vivo TA datasets. These advances establish in vivo TA spectroscopy as a versatile technique for studying energy and charge transfer in living systems.
