Mechanism of low power laser irradiation on red blood cell deformability

The effects of laser irradiation on erythrocyte deformability and related mechanism were investigated. Membrane attached hemoglobin (Hbm) is the determinant factor of erythrocyte deformability. After irradiation of 532 nm (30 mW, 20 minutes) or 632.8 nm (30 mW, 60 minutes), the content of Hbm lowere
