: The primary engines of cellular respiration produce the highest concentration of ROS, making them the leading source of biophotonic signals.
Ultimately, biophoton detection is likely to be most useful when combined with other non‑invasive measures, such as heart rate variability, electrodermal activity, and thermal imaging, within a multi‑modal health assessment framework. light in shaping life biophotons in biology and medicine pdf
Detecting biophotons requires extraordinary sensitivity, as emission intensities range from about 2 to 200 photons per second per square centimeter—far below the threshold of human vision. Several technologies have been developed to meet this challenge. : The primary engines of cellular respiration produce
Living systems use these light signals for . such as heart rate variability
