SEM images of electrospun 2D and 3D scaffolds after post-treatment (annealing and crosslinking): (a) electrospun FAQ(LDLK)3gp lamina and channel show rough surface with fibers connection, (b) electrospun FAQ(LDLK)3gp-sds lamina and channel with more uniformity of fibers and surface after adding a surfactant, (c) electrospun FAQ(LDLK)3gp-HYDROSAPgp lamina and channel comprise defect-free fibers and even surface, (d) electrospun FAQ(LDLK)3gp-HYDROSAPgp-sds lamina and channel reveals very uniform fibers and surface after adding SDS and HYDROSAP (left: 2D lamina, right: 3D microchannels).
