Non-Thermal Biological Effect of Graphene Far-Infrared Ray on <i>Saccharomyces cerevisiae</i> Cells

Graphene materials can emit far-infrared ray, but the biological effects of graphene ray have not been studied. Furthermore, non-thermal effect on organism has systematically studied independently thermal effect. The purpose this study was to investigate (gFIR) Saccharomyces cerevisiae cells. In work, stringent control cultivation conditions carried out ensure stability and constancy culture its temperature. Flow cytometry used detect gFIR irradiation cell membrane permeability, mitochondrial potential (MMP) intracellular reactive oxygen species (ROS) content. Compared with group, permeability exposure cells decreased by 4.7%, MMP increased 16% ROS reduced 10.7%. results revealed valuable features cells, further analysis demonstrated that should great application value in disease prevention health promotion.
