cross-sectional areas of the microfibers were investigated. shown in Figure 2B, when the sample flow rate was 80 μL/
As shown in Figure 2A, when the sheath flow rate was 160 min, the sheath flow rate increased from 120 to 200 μL/min,
μL/min and the sample flow rate was increased from 50 to and the microfiber cross-sectional area decreased with an
110 μL/min, the microfiber cross-sectional area increased increase in the sheath flow rate. This situation is similar
with the increase of the sample flow rate. In contrast, as to findings reported in previous studies. 26,46 However, it is
