Fig. 3From: Modification and optimization of electrospun gelatin sheets by electron beam irradiation for soft tissue engineeringSEM images of the crosslinked gelatin fibrous sheet (a) and e-beam-irradiated gelatin sheets with applied doses of 100 (b), 200 (c), 300 (d), 400 (e), 500 (f), and 600 kGy (g). All nanofibers were crosslinked by glutaraldehyde vapor before e-beam irradiation. Scale bars are 10 μmBack to article page
