1. Two-years studying in University of California at Berkeley as a visiting student researcher
In the past two years, Mr. Bing Zhang was supported by CSC and performed his research work as a visiting student supervised by Prof. Liwei Lin at the Department of Mechanical Engineering, University of California, Berkeley, USA. His research interests mainly focus on electrohydrodynamic 3D printing technique and its applications in related fields like tissue engineering and energy storage. In the presentation, Mr. Bing Zhang will share his research and studying experience during the past two years in the US. In addition, the living and cultural experience will also be presented.

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.
