(A1) Rhodamine 6G loading kinetics and (A2) release profiles of polydopamine-coated PCL fiber samples in aqueous solutions at pH 2.0, 5.0, 7.0, 9.0 and 11.0. (B1) Doxorubicin loading kinetics and (B2) release profiles of polydopamine-coated PCL fiber samples in aqueous solutions at pH 2.0, 5.0, 7.0 and 9.0. The in vitro release data were fitted with a desorption model. L2.0: α = 0.74, τr = 0.24; L5.0: α = 0.46, τr = 0.22; L7.0: α = 0.09, τr = 0.51; L9.0: α = 0.08, τr = 0.47. H1299 cell viability quantified by MTT assay treated with release media for (C1) 1 day and (C2) 3 days. The released media from doxorubicin-loaded, polydopamine-coated PCL fiber samples were collected at different times (3 min, 20 min and 120 min) from solutions with pH 2.0, 5.0, 7.0 and 9.0 (*p < 0.05, **p < 0.01).
