Title: Electrohydrodynamic printing of sub-microscale fibrous architectures with improved cell adhesion capacity

Authors: Bing Zhang, Jiankang He*, Qi Lei, Dichen Li

Abstract: Electrohydrodynamic (EHD) printing is emerging as an innovative additive manufacturing strategy to fabricate high-resolution fibrous scaffolds that provide necessary mechanical cues to guide the growth of attached cells. However, the size of the EHD-printed fibers based on biopolymers was mainly limited to several microns, which cannot fully mimic the sub-microscale architectures of native extracellular matrix. Here solution-based high-resolution EHD printing in the cone-jetting mode was improved to fabricate sub-microscale biopolymeric fibers for enhanced cell adhesion capability. The results indicate that sub-microscale fibers significantly improve cell adhesion, spreading and orientation in comparison with microscale PCL fibers fabricated by melt-based EHD printing. Multilayer fibrous structures can also be obtained by stacking the EHD-printed sub-microscale fibers in a layer-by-layer manner. The proposed method might provide a promising approach to reproducibly print well-organized sub-microscale architectures for tissue regeneration.
