Living organisms emit ultraweak photons when exposed to light, a phenomenon linked to their physiological condition. This study explores the characteristics and physical dependencies of this photon emission.

Area of Science:

  • Biophysics
  • Quantum Biology
  • Photobiology

Background:

  • Living organisms exhibit photoinduced ultraweak photon emission (UPE).
  • This UPE occurs in the seconds timescale.
  • The phenomenon's relationship with biological system function is under investigation.

Purpose of the Study:

  • To describe photoinduced ultraweak photon emission in living organisms.
  • To discuss the characteristics and physical parameter dependencies of UPE.
  • To present experimental evidence linking UPE to biological system functional state.

Main Methods:

  • Observation of photon emission from various living organisms.
  • Analysis of emission characteristics.
  • Investigation of dependencies on physical parameters.

Main Results:

  • Photoinduced ultraweak photon emission was observed in the seconds timescale.
  • Characteristics of UPE and its dependence on physical parameters were analyzed.
  • Experimental evidence suggests a connection between UPE and biological system function.

Conclusions:

  • Photoinduced ultraweak photon emission is a measurable phenomenon in living systems.
  • UPE characteristics are influenced by physical parameters.
  • UPE serves as a potential indicator of biological system functional state.
