Biophoton Emission: Experimental Background and Theoretical Approaches

Biophoton emission is a general phenomenon of living systems. It concerns a weak photon radiation from a few to some hundred photons per second, per square centimeter surface area, at least within the spectral region from 200 to 800 nm. The results indicate that biophoton emission can be assigned to a coherent field within living organisms, its functions being intra and intercellular regulation and communication. This review deals with some central results and their interpretation.
