Mechanical response of RBCs under static tensile loading. (A) Variation of relative stretch ratio as a function of time of 2 representative cells, #1 and #2, under the static loading at a constant voltage level of 1.2 V. (B–D) Values of εp, μ, and η of cells (n = 20) measured at 10, 20, 30, 40, and 50 min, respectively. ***P < 0.001; n.s., nonsignificant. Note the results here for static loading at the voltage of 1.2 V for 50 min correspond approximately to that obtained for cyclic loading with only 25 min of accumulated loading time at 1.2 V for 750 fatigue cycles (at a frequency of 0.25 Hz).
