2020 Spring Seminar Series: Bioscience and Bioengineering
3D Bioprinting has received significant attention due to its effortless customization and flexibility to construct artificial tissues and organs. The technique requires a biocompatible ink that may contain biologically active components to support the encapsulation and maintenance of viable cells. In recent years, several biomaterials, primarily natural and synthetic hydrogels, have been studied for their potential application as bioinks. These bioinks ideally should be able to transform from flowing, liquid-like state to a gelled, solid-like state spontaneously, whether processed through extrusion or lithography bioprinting. In this talk, we will discuss different bioinks that are currently used for Bioprinting and the significant challenges in designing novel bioinks. Moreover, I will introduce our recent work on developing ultrashort peptides as bioinks. We found that the printed structure from peptide bioink had adequate mechanical strength, shape fidelity, and excellent biocompatibility for different cell lines, including human dermal fibroblast cells and human mesenchymal stem cells.
Bio: Hepi Hari Susapto is a Ph.D. student working in the Laboratory for Nanomedicine under the supervision of Prof. Charlotte Hauser. He earned his Bachelor's degree in Chemistry at Middle East Technical University, Turkey, in 2012. He then gained a scholarship from The Scientific and Technology Research Council of Turkey for his master's degree in Materials Science (2013-2015) at Bilkent University, Turkey. Since then, he has been working on peptide hydrogel for various applications in tissue engineering and biomedicine.
