Fig. 1

Scanning electron micrographs of zein nanofibers incorporated with various concentrations of progesterone, a without progesterone. Red arrows indicate the smooth and uniform surface morphology of nanofibers. Its shows not containing progesterone; b 1.2 g progesterone. Yellow arrows indicate the progesterone impregnated in the nanofibers; c 1.9 g progesterone, d 2.5 g progesterone. Blue arrows indicate the high concentration of progesterone disrupting the nanofiber structure
