Light is fundamental to life, from powering photosynthesis to regulating circadian rhythms. Beyond classical photobiology, the discovery of ultraweak photon emissions—biophotons—has opened a subtle, information-rich frontier linking physics, chemistry, and physiology. This essay synthesizes current understanding of biophotons, their proposed roles in cellular organization and communication, mechanisms of generation and detection, implications for medicine, and key open questions ripe for research.
In his comprehensive work, Light in Shaping Life: Biophotons in Biology and Medicine
The phrase is most directly illustrated in embryogenesis and morphogenesis. How does a single fertilized egg develop into a complex organism with spatial precision?
Biophotons are not random thermal emissions. Unlike chemiluminescence or bioluminescence (e.g., fireflies), biophoton emission is:
