Swelling, weight loss, and wettability of electrospun fiber scaffolds when in contact with a buffer for different time periods. (A) Swelling index of all fiber scaffolds; (B) weight loss of all fiber scaffolds; and (C) contact angles of all fiber scaffolds at the start of the experiment and after 30 s. Data are presented as mean ± SD (N = 3). * Statistical significance, p < 0.05. MF = microfiber; NF = nanofiber.
