Abstract

Proteins in aqueous solution are complex systems that are made of many interacting and non-interacting elements whose behavior can be predictable upon the application of non-linear models. The aim of this study was to show that this complex system behaves like a viscoelastic system under exposure to high frequency electromagnetic (HF-EMF). To this aim, typical proteins in water solution were exposed for 3 h to a high frequency electromagnetic field at the power density of 1 W/m2.  Proteins α-helices aligned along the direction of the field and the integrated areas of proteins β-sheet content increased linearly as a function of proteins dipole moment. This result can be explained assuming that proteins in aqueous solution under HF-EMF behave like a viscoelastic system.
