**About the Special Issue Editors**

**Dong-Wook Han** (Prof.) obtained his B.S. in the Department of Biochemistry at Yonsei University, Seoul, in 1998. He completed his M.S. and Ph.D. degrees in the graduate program of biomedical engineering from Yonsei University in 2000 and 2004, respectively. With two and a half years of experience as a postdoctoral fellow (under the supervision of Prof. Suong-Hyu Hyon) at the Institute for Frontier Medical Sciences, Kyoto University, Japan, Dr. Han returned to Korea. In 2008, he joined the faculty of Pusan National University (PNU) where he began his academic career as an assistant professor and is currently a full professor and chair in the Department of Optics and Mechatronics Engineering at PNU. Dr. Han is serving as a board member of several biomedical societies and an editorial board member of many scientific journals including BioMed Research International, Nanomaterials, World Journal of Stem Cells, Journal of Nanotheranostics, Biomaterials Research, etc. Since 2008, he has authored or co-authored over 120 scientific publications, possesses over 10 international and national patents, and jointly authored several book chapters. His research interest concerns BT–NT convergence, especially tissue engineering and regenerative/translational medicine using smart nanobiomaterials; development of artificial tissues/organs, medical devices, and organs-on-chips; 3D bioprinting; cell imaging; and evaluation of biocompatibility and nanotoxicity.

**Timur Sh. Atabaev** (Assistant Prof.) received his Ph.D. degree (nanoscience and nanotechnology, under the supervision of Profs. Yoon-Hwae Hwang and Hyung Kook Kim) at Pusan National University (South Korea) in 2012. From 2012 to 2017, he worked as a postdoctoral fellow and research professor both at Pusan National University and Seoul National University. Since 2017, he has been an Assistant Professor in Chemistry at Nazarbayev University, Kazakhstan. His areas of specialization include multifunctional materials and advanced nanostructures for biomedical, optical, energy, sensing, and photocatalytic applications. He has delivered several invited talks and served as a committee member for numerous international meetings. He is a member of the American Chemical Society and Royal Society of Chemistry. He was a recipient of the Young Researcher of the Year Scopus 2018 award.
