The joint research team led by Principal Researcher Dr. Joo-Yun Jung of the Nano-Convergence Mechanical Systems Research Division at KIMM and Professor Jongwon Lee of UNIST developed a metamaterial that enhances infrared absorption spectroscopy through 100-fold amplification of detection signals. The proposed metamaterial is a special functional material with vertical nanogaps of a smaller size than

Biological artificial organs like skin, vessels now produced more easily

The fabricated membrane was transferred to a 12-well insert for cell co-culture to mimic. view more  Credit: Korea Institute of Science and Technology(KIST) A Korean research group has developed a technology that allows for the differentiation of stem cells into desired cell types, such as vascular mural cells or osteoblasts, without special pretreatment. This technology is expected to facilitate the production of artificial organs for preclinical studies or artificial tissues for transplants such as artificial skin and cardiac patches. The Korea Institute of Science and Technology (KIST) announced that the research group led by Dr. Youngmee Jung of the Center for Biomaterials has developed a new cell co-culture platform based on porous, ultrathin membranes that can culture multiple types of cells simultaneously to form tissues similar to those
