The organoid according to the present invention can maintain a high level of structural stability and bio-fidelity by reproducing a cell arrangement and microenvironment similar to those of actual lung tissue. The multi-tissue organoid more precisely reproduces a microenvironment in which epithelial tissues and interstitial tissues are arranged in layers as in a living body, rather than adopting a simple cell mixing method, and thus can be used in various biomedical applications, such as regenerative medicine, research on lung disease conditions, and evaluation of responsiveness to anticancer drugs and anti-fibrotic drugs. In addition, the present invention has excellent expandability to organoid-on-chip technology or bio-artificial organ development, and thus can be expected to be used as a precision medicine and next-generation cell therapy platform. https://scholar.dgist.ac.kr/handle/20.500.11750/59299 Title: 자궁경부 오가노이드의 제조방법 및 이의 용도 Author(s): 이바울; 정영태 Abstract: 본 발명은 자궁경부 오가노이드의 제조방법 및 이의 용도에 관한 것으로 자궁경부의 중층편평상피 (stratified squamous epithelium) 을 재현하는 자궁경부 오가노이드 제조용 배지 및 제조 방법을 제공하며, 이를 활용하여 자궁경부 오가노이드의 장기 계대배양을 가능케 하며, 약물 처리 플랫폼으로 활용할 수 있다. https://scholar.dgist.ac.kr/handle/20.500.11750/59285 Title: Ultra-thin high-resolution transfer-printed breathable electronics for conformal wearable devices Author(s): Choi, Hyeokjoo; Lee, Dongju; Hwang, Sieun; Shin, Juhee; Bae, Jihoon; Jang, Gain; Kwon, Seokhun; Kang, Hyunil; Myeong, Jihyeon; Jeong, Youngtae; Roh, Jong Wook; Lee, Sungwon Abstract: Nanomesh electronics offer remarkable potential for biomedical and human–machine interface applications due to their conformability to nonplanar surfaces, versatile functionality, and long-term reliability. However, existing materials face significant challenges related to surface structure and chemical resistance, resulting in high electrical resistance and complex fabrication requirements. To address these challenges, we present transfer-printed nanomesh electrodes (NEs) produced by integrating fine-patterned 2D electrodes with porous nanomesh. Electrospun thermoplastic-polyurethane nanofibers provide strong adhesion to the electrodes, which generate sufficient force (95.1 mN∙cm−1) to maintain structural integrity and electrical performance. Unlike direct deposition, which requires a minimum thickness of 100nm to achieve 14.12±2 mS, transfer-printed NEs reach 16.91±8.7 mS only with 20nm. Furthermore, our electrodes demonstrate excellent durability under deformation, maintaining stable electrical performance with only a 0.53% change at a bending radius of 1mm. To validate their practical application, we demonstrate a NE-based tactile sensor, which exhibits a conductance change from 0 mS in the normal state to 130 mS upon touch. These results highlight the potential of transfer-printed NEs for next-generation e-skin with fine patterning, high conductivity, and long-term reliability. In addition, our novel method addresses the challenges of manufacturing breathable devices with functionalities extending beyond simple electrodes. 2025-11-30T15:00:00Z
