Paper Abstract

Raman tweezers spectroscopy study of effect of free radicals was carried out on erythrocytes. We prepared hydroxyl radicals using Fenton reaction (which yields hydroxyl radicals). Raman spectra were acquired from single, trapped erythrocytes after supplementing with these free radicals. The changes in the Raman bands such as 1211 cm-1, 1224 cm-1, 1375 cm-1 indicate deoxygenation of red blood cells (RBCs). Our study shows that free radicals can induce oxidative stress on erythrocytes. The changes in the Raman spectra as well as shape of erythrocytes indicate that oxidative stress can trigger eryptosis in erythrocytes.
