As shown in the representative SEM imaging (Fig. 1), at the same
polymer concentration (10% SPI and 1% PEO), fibers electrospun from
SPI fiber-forming solutions with ARRE extract added before (SPI-ARRE
B/D, Fig. 1b) and after (SPI-ARRE A/D, Fig. 1a) protein denaturation did
not result in noticeable morphological differences (overall seen as
