ABSTRACT In the present work the thermostability and fluorescence peculiarities of the methylene blue complexes with human serum albumin have been studied under the effect of millimeter range electromagnetic waves. For this aim the denaturation of the complexes was measured using the double-beam spectrophotometer Unicam-SP8-100 and the fluorescence measurements were carried out on the spectrofluorometer Cary Eclipse. The albumin solutions were irradiated by electromagnetic waves with 41.8 and 51.8 GHz frequencies. The irradiation was shown to result in the thermostability increasing of the complexes and this effect depends on the frequency. It was also revealed that at the irradiation the fluorescence properties of the methylene blue complexes with albumin change, which, in turn, is connected to the alteration of the protein folding.
