Figure 2. — The contact angles of the fibrous scaffolds. (a) PLGA fibrous scaffold. (b) PLGA/0.01% icariin fibrous scaffold. (c) PLGA/0.1% icariin fibrous scaffold. (d) PLGA/1% icariin fibrous scaffold. The contact angle of pristine PLGA was 85.47 ± 4.84°, and it decreased gradually from 81.28 ± 11.47° to 67.62 ± 1.52° with the gradual increase in icariin concentration.
