摘要: Abstract Biophotons spontaneously emitted from radish root cells were detected using highly sensitive photomultiplier tube. Freshly isolated exhibited spontaneous photon emission of about 4 counts s −1 . Addition hydrogen peroxide to the caused significant enhancement in biophoton 500 counts s Removal molecular oxygen glucose/glucose oxidase system and scavengering reactive species by reducing agents such are sodium ascorbate cysteine completely diminished emission. Spectral analysis peroxide-induced indicates that biophotons mainly green–red region spectra. The data provided electron paramagnetic resonance spin-trapping technique showed formation singlet observed after addition H 2 O correlates with These observations provide direct evidence is involved cells.
