Bio-Information Detection Using Biophoton Measurements

Biophoton emissions are the ultraweak chemiluminescence observable from any living system. The origin of the biophoton is the reactive oxygen species (ROS) produced in biochemical reactions and metabolic processes, such as mitochondrial aerobic respiration. Usually, toxic ROS are detoxified by ROS scavengers within the living systems, and almost no biophotons are detected. When living systems suffer from unpleasant circumstances, however, such as environmental and biological stress, the concentration of ROS increases. As a result more biophotons are radiated. Therefore, the intensity of biophotons in space and time can be used to understand the bio-information and current status of living systems without incurring any external perturbation or damage. In other words, one can evaluate physiological circumstances in real time based on biophoton measurements.
