Pukyong National University Professor Nam Seung Yun’s Team Develops Elasticity Monitoring-Based Bioprinting Technology
- World’s First Real-Time Elasticity Monitoring-Based Bioprinting Technology
Pukyong National University (President Bae Sang-Hoon) announced that the research team led by Professor Nam Seung Yun of the Department of Biomedical Engineering has developed a new bioprinting technology using ultrasound elasticity monitoring.
Professor Nam Seung Yun, along with Professor Park Sang-Hyug from the same department and Professor Yoon Changhan from the Department of Biomedical Engineering at Inje University, successfully developed the world’s first technology that precisely measures the elasticity changes of cell scaffolds in real-time during the bioprinting process using ultrasonic shear wave elastography.
Bioprinting is an advanced technology for tissue regeneration and artificial organ development, but there have been limitations in precisely evaluating the mechanical properties of cell scaffolds in real time.
Human tissues have varying elastic properties, and since the growth and differentiation of cells are greatly influenced by these mechanical characteristics, the development of a technology to dynamically monitor them is essential.
Conventional methods can only assess the mechanical properties destructively before and after the fabrication of the cell scaffold, making it difficult to capture dynamic changes during the bioprinting process. However, the technology developed by the research team has the advantage of enabling non-destructive monitoring of the elasticity and stability of the structure even during the fabrication of the cell scaffolds.
The research team published their findings in the paper titled “Suspended bioprinting with in-situ elasticity monitoring using the assessment of shear wave phase velocity” in the top-tier international journal <Additive Manufacturing> (IF 10.3, JCR top 5.8%) in February.
Professor Nam Seung Yun stated, “This research is expected to serve as a key technology for quality control and process optimization in the field of bioprinting. In particular, by enabling long-term tracking and measurement of mechanical property changes in real time for the same sample, it can reduce measurement errors and enhance cost-effectiveness, contributing to innovative advancements in tissue engineering and biomaterials.”
This research was supported by the Ministry of Health and Welfare’s Project of Biomaterial Development for Human Implantation (RS-2022-KH129323, principal investigator: Professor Chung Eun-Jae at Seoul National University Hospital).
