Abstract

Overview

Raman spectroscopy explores the impact of GSM 900 MHz and 1800 MHz mobile phone signals on human red blood cells (RBCs). This study addresses crucial alterations in the physical properties of RBCs when exposed to mobile phone emissions.

Findings

• Exposure leads to a decrease in hemoglobin-oxygen affinity in RBCs.
• Possible mechanisms include the activation of voltage-gated membrane Ca2+ channels, heightening adenosine triphosphate (ATP) and 2,3-diphosphoglycerate (2,3-DPG) levels.
• Confirmatory tests with fluorescent Ca2+ indicators showed elevated intracellular Ca2+ levels in exposed RBCs.
• Further investigations using diffraction phase microscopy and optical tweezers showed notable changes in the shape and mechanical properties of the RBCs due to mobile signal exposure.

Conclusion

The study indicates substantial cellular alterations due to mobile phone emissions, suggesting potential health risks linked to prolonged exposure, underscoring the need for further research into its long-term effects.
