A local research team, comprised of members of the Korea Institute of Machinery and Materials(KIMM) under the Ministry of Science and ICT and UNIST, developed a metamaterial absorber that significantly enhances the detection of harmful substances or biomolecules, and published their results in
Small Methods.
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 ....

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 tissue ....

Advances in wearable devices have enabled e-textiles, which fuse lightweight and comfortable textiles with smart electronics, and are garnering attention as the next-generation wearable technology. In particular, fiber electronic devices endowed with electrical properties, while retaining the specific characteristics of textiles, are key elements in manufacturing e-textiles.
Optoelectronic devices are generally constructed using layers of semiconductors, electrodes, and insulators; their performance is greatly affected by the size and structure of the electrodes. Fiber electronic components for e-textiles need to be fabricated on thin, pl ....
