Delayed luminescence (DL) in biological systems may arise from decaying electron states within ordered cellular structures. This finding suggests DL measurements can serve as a novel biophysical investigation tool.

Area of Science:

  • Biophysics
  • Cell Biology
  • Solid-State Physics

Background:

  • Delayed luminescence (DL) is observed in biological systems.
  • The characteristics of biological DL share similarities with solid-state systems.

Purpose of the Study:

  • Analyze the main characteristics of seconds-range delayed luminescence in biological systems.
  • Investigate the connection between DL and cellular organization.
  • Explore the potential of DL as a biophysical probe.

Main Methods:

  • Analysis of delayed luminescence (DL) in biological systems.
  • Comparison of biological DL with solid-state DL characteristics.
  • Application of a proposed soliton model.

Main Results:

  • DL in biological systems correlates with changes in cell organization.
  • Biological DL characteristics resemble those of solid-state systems.
  • DL may originate from the decay of collective electron states in ordered macromolecular structures.

Conclusions:

  • Delayed luminescence in biological systems is linked to collective electron state decay during energy and charge transport.
  • DL measurements show potential as an intrinsic probe for biophysical investigations.
