Proposed Physical Mechanism
Chemi-excitation via oxidative stress by reactive oxygen species(ROS) and/or catalysis by enzymes (i.e. peroxidase, lipoxygenase) is a common event in the biomolecular milieu. Such reactions can lead to the formation of triplet excited species, which release photons upon returning to a lower energy level in a process analogous to phosphorescence. That this process is a contributing factor to spontaneous biophoton emission has been indicated by studies demonstrating that biophoton emission can be attenuated by depleting assayed tissue of antioxidants or by addition of carbonyl derivitizing agents. Further support is provided by studies indicating that emission can be increased by addition of reactive oxygen species (ROS).

Famous quotes containing the words proposed, physical and/or mechanism:
“There never seems to be any difficulty in stretching the laws and the constitution to fit any kind of a political deal, but when it is proposed to make some concession to women they loom up like an unscalable wall.”
—Susan B. Anthony (1820–1906)
“Toddlerhood resembles adolescence because of the rapidity of physical growth and because of the impulse to break loose of parental boundaries. At both ages, the struggle for independence exists hand in hand with the often hidden wish to be contained and protected while striving to move forward in the world. How parents and toddlers negotiate their differences sets the stage for their ability to remain partners during childhood and through the rebellions of the teenage years.”
—Alicia F. Lieberman (20th century)
“A mechanism of some kind stands between us and almost every act of our lives.”
—Sarah Patton Boyle, U.S. civil rights activist and author. The Desegregated Heart, part 3, ch. 2 (1962)
