Abstract:

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.
