Elucidating the energetic processes which govern photosynthesis, the engine of life on earth, are an essential goal both for fundamental research and for cutting-edge biotechnological applications. Fluorescent signal of photosynthetic markers has long been utilised in this endeavour. In this research we demonstrate the use of fluorescent noise analysis to reveal further layers of intricacy in photosynthetic energy transfer. While noise is a common tool analysing dynamics in physics and engineering, its application in biology has thus far been limited. Here, a distinct behaviour in photosynthetic pigments across various chemical and biological environments is measured. These changes seem to elucidate quantum effects governing the generation of oxidative radicals. Although our method offers insights, it is important to note that the interpretation should be further validated expertly to support as conclusive theory. This innovative method is simple, non-invasive, and immediate, making it a promising tool to uncover further, more complex energetic events in photosynthesis, with potential uses in environmental monitoring, agriculture, and food-tech.
阐明主宰地球上生命引擎的光合作用的能量过程，既是基础研究的重要目标，也是前沿生物技术应用的关键目标。长期以来，光合标记物的荧光信号一直被用于这一研究。在这项研究中，我们展示了荧光噪声分析在揭示光合作用能量传递中更复杂层次的应用。尽管噪声是分析物理和工程动力学的常用工具，但它在生物学中的应用迄今为止一直受到限制。在这里，我们在各种化学和生物环境中测量了光合色素的明显变化。这些变化似乎阐明了控制氧化自由基产生的量子效应。虽然我们的方法提供了一些见解，但需要注意的是，解释应该由专家进一步验证，以支持更具结论性的理论。这种创新方法简单、非侵入性和即时，有望成为揭示光合作用中更复杂能量事件的有力工具，在环境监测、农业和食品技术等领域具有潜在用途。
