Abstract: 
The "biological engine" of living cells is electromagnetic energy. Activated by light, which consists of photons, firstly described by Einstein in 1905, they generate electrical charges, which activate cellular and tissue reactions. They can be modulated by the application of local external electromagnetic energy.G.
