Figure 3. The main principles of light application in biomedicine.
(A) Photosensitizers absorb blue light and UVA and then modulate
mitochondrial ROS production and affect oxidative stress, metabolism,
apoptosis and DNA oxidative damage. (B) UVB causes direct damage to DNA
production and can produce cancer-inhibiting effects after light
absorption by exogenous photosensitizers. (C) UVB through the skin to
achieve the regulation of Vitamin D affects Calcium phosphorus, through
the absorption of photosensitizers in the organism can achieve
therapeutic effects. (D) UV, blue light and laser are transmitted
through eye - nervous system - hypophysis - spine to endocrine organs to
achieve endocrine and biorhythmic effects.
