Photobiomodulation: The Forth Side of Tissue Engineering Foursquare

[摘要] 2015 was named the International Year of Light andLight-based Technologies by the United Nations, initiatedby different scientific societies in collaboration withUNESCO. This initiative shed light on the importanceof light and light-based technologies and their positiveeffects on solving various challenges in such topics asagriculture, energy, education, and health.1 However, as“light scientists,” we have perfected our focus and practicesto fulfill their potential. Photochemistry is a subspecialtyof chemistry focusing on the chemical reactionswhich occur by the atoms’ light absorption. Differentexamples of photochemistry are vitamin D productionwith sunlight, photosynthesis, and vision initiation byrhodopsin. Photobiomodulation (PBM) is a mechanismin which a nonionizing visible or near-infrared lightform is absorbed by endogenous chromophores causingphotochemical and photophysical reactions on differentlevels of biological scales without causing any thermaldamage. PBM therapy is a photon-based therapy basedon the fundamentals of PBM. Various light sources suchas lasers, broadband light, and light-emitting diodes(LEDs) in the near-infrared and visible spectrum can beused for this matter.
