Biological mechanisms and applications of photobiomodulation in wound care
Photobiomodulation (PBM) uses specific wavelengths and light intensities to stimulate biological processes within cells, offering a non-invasive method of initiating wound repair. At a cellular level, PBM modulates signalling molecules such as reactive oxygen species and displaces nitric oxide from cytochrome c oxidase in mitochondria, allowing cells to resume signalling and ATP synthesis. This mechanism holds merit as an adjunct to treatments for chronic wounds and radiation-induced fibrosis (RIF). Chronic wounds, …
