Interaction of laser with molecular tissues a free radical complex result

Interaction of laser with molecular tissues a free radical complex result, which has different effects on tissues. This radical has free-moving electrons, which affect the physiological process hence, pathological change occurs in tissues. On the other hand, the molecular chemical structure of tissue fluids and proteins in the body may be destroyed (Huang, Zhao, Zhong, Guo and Sun, 1997, pp.315-325). Laser radiations also cause biologically stimulating effects on blood cells, enzymes, and metabolic energies of tissues. Proteins are able to cross-link with laser radiations causing complications in the body of living organisms. Clinical studies have shown that, apart from the normal negative laser effects, lasers can also be instrumental in healing processes. It is important to note that, different types of lasers induce different effects, which can be positive or negative. Lasers of high intensity can cause scattering and damage to body cells and tissues, whereas low-intensity laser irradiations are applicable in medicine for treatment purposes. Light from a laser source can penetrate into tissues to enhance cell-reproduction and generation. This happens due to the fact that a laser beam can provide energy, which is essential in repairing and regenerating tissue growth and strengthening the muscles.
