- Microfluidic Generation of Exosome-Mimetic Nanoparticles for Scalable Production and Enhanced Therapeutic Efficacy
- Microfluidic Generation of Exosome-Mimetic Nanoparticles for Scalable Production and Enhanced Therapeutic Efficacy The research team led by professor Hyo-Il Jung from the Department of Mechanical Engineering (co-first authors: Jaejeung Kim, Do Hyun Lee, Hyunjo Seo), has successfully established a microfluidic platform enabling continuous and scalable synthesis of exosome-mimetic nanoparticles (ENPs). The team designed a reverse-Tesla structured microfluidic chip that maximizes the mixing efficiency of the nanoparticle generating solutions within the channel, achieving stable and homogeneous ENP synthesis. Furthermore,the researchers fabricated ENPs mimicking the lipid components of salivary gland stem cell-derived exosomes and encapsulating two antifibrotic microRNAs, which enhanced cellular uptake efficiency and wound healing performance compared to natural exosomes. Remarkably, this system achieved a production rate approximately 80,000 times faster than exosome isolation methods. This study, recognized as a core enabling technology for the commercialization of exosome-based therapeutics, was published in 'Small' (Impact Factor: 12.1, October 2025).

- Development of AuNPs–CNT-based flexible tactile sensor with high sensitivity (2025.10.13)
- Development of AuNPs–CNT-based flexible tactile sensor with high sensitivity A research team, led by Professor Jongbaeg Kim from the Department of Mechanical Engineering has developed a flexible tactile sensor that simultaneously achieves high sensitivity and a wide pressure-sensing range by coating carbon nanotubes (CNTs)—onto which gold nanoparticles (AuNPs) were directly precipitated—onto a three-dimensional porous polymer sponge structure. Conventional flexible tactile sensors have faced a fundamental trade-off: enhancing sensitivity typically narrows the measurable pressure range, whereas broadening the pressure range reduces sensitivity, limiting their practical utility. The research team addressed this challenge by combining zero-dimensional AuNPs and one-dimensional CNTs to maximize variations in contact resistance. As a result, the sensor demonstrated a low detection limit (~50 Pa), low hysteresis, fast response, and excellent durability. Moreover, the device successfully measured various physiological and motion signals, such as pulse waves and gait, demonstrating its potential applicability in wearable healthcare. The study was published in the prestigious nanoscience journal Microsystems & Nanoengineering (ranked #1 in INSTRUMENTS & INSTRUMENTATION).

- Made of Light: Slippery 3D Surfaces That Control Liquids with Ease (2025.10.10)
- Made of Light: Slippery 3D Surfaces That Control Liquids with Ease The research team led by Prof. Seok Kim from the Department of Mechanical Engineering at Yonsei University, in collaboration with Professor Young Tae Cho and his team at Changwon National University, have developed a three-dimensional slippery surface that dramatically reduces the adhesion of materials using light. This achievement marks the world’s first realization of a lubricant-infused slippery surface inspired by natural examples such as lotus leaves and pitcher plants in a 3D structure. By combining digital light processing (DLP) 3D printing with photo-curable chemical bonding techniques, the team successfully fabricated 3D surfaces where various liquids, including water, oil, serum, and even honey, flow with almost no resistance, and ice detaches easily. They further demonstrated a microfluidic SlipChip, where droplets autonomously move and mix without external energy input, suggesting promising applications in bio-diagnostic and drug-testing platforms. This study was conducted through international collaboration with Harvard Medical School, MIT, and the University of Hong Kong, and was published in Nature Communications (IF 15.7, Top 7% in Multidisciplinary Sciences) on October 10, 2025. Furthermore, the research was featured as a Research Highlight in Nature Reviews Materials (IF 87.1, Top 0.1% in Multidisciplinary Sciences), recognizing its scientific excellence.

- Development of washable and heat-resistant cotton-based e-textile by inkjet printing (2025.09.29)
- Development of washable and heat-resistant cotton-based e-textile by inkjet printing The research team, led by Professor Jongbaeg Kim from the Department of Mechanical Engineering has developed an electronic textile (e-textile) that maintains the breathability and flexibility of the fabric while precisely dispensing small quantities of carbon nanotube ink and particle-free reactive silver ink onto cotton fabric using an inkjet printing process. E-textiles are gaining attention as a core technology for next-generation wearable platforms, incorporating electronic functionality into comfortable fabrics. However, conventional e-textile manufacturing methods suffer from limitations: thick coating layers reduce the inherent breathability and comfort of the fabric, and the low bonding strength between the coated conductive material and the fiber makes the e-textile susceptible to external environmental influences. In this study, the research team treated the fiber surface with poly-L-lysine, a positively charged, biocompatible polymer, to ensure strong adhesion through ionic bonding between the negatively charged conductive nanomaterial and cotton fiber. This enabled the team to overcome the durability issues of existing e-textiles. The fabricated electronic fibers maintained their conductive properties even under mechanical deformation, such as bending and twisting, and maintained stable performance even after 10 washes in a household washing machine. Furthermore, the fabricated electronic fibers were applied as high-sensitivity pressure sensors and high-performance heating elements, demonstrating their potential for use in wearable devices. The results of this study were published in Nature Communications, a renowned international scientific journal. The link: https://doi.org/10.1038/s41467-025-63636-3

- A Novel Design Strategy for Realizing High-Safety and High-Efficiency Zinc–Halogen Batteries (2025.09.11)
- A Novel Design Strategy for Realizing High-Safety and High-Efficiency Zinc–Halogen Batteries The research team, led by Professor Seong Chan Jun from the Department of Mechanical Engineering (first author: Jongwoo Hong, co-authors: Junghyun Joo and Taehyeon Kim), has proposed a key design principle for high-stability aqueous zinc–halogen batteries as a new alternative to overcome the safety limitations and high manufacturing costs of conventional lithium-ion batteries. Zinc–halogen batteries, which utilize water-based electrolytes, eliminate fire hazards and achieve both cost-effectiveness and safety, making them a promising next-generation energy storage system (ESS). The research team significantly enhanced the reaction kinetics and maximized the energy efficiency of zinc–halogen batteries through a Confinement–Catalysis–Conduction strategy. In particular, by precisely controlling the movement of halogen ions within the electrode, the team achieved both long-term durability and high stability. This study elucidated the correlation between the structural characteristics and electrochemical performance of halogen electrodes, providing a new design guideline for the development of high-performance aqueous batteries. The research was published in the internationally renowned journal Chemical Society Reviews (Impact Factor: 39.3, Top 1.26%) and was selected as the cover article in recognition of its outstanding contribution.

- Enhanced Cyclic Stability of Transition Metal Phosphide Electrodes in Alkaline Electrolytes via 1D–1D Core–Shell Design
- Enhanced Cyclic Stability of Transition Metal Phosphide Electrodes in Alkaline Electrolytes via 1D–1D Core–Shell Design The research team, led by Professor Seong Chan Jun from the Department of Mechanical Engineering (first author: Jongwoo Hong, co-authors: Junghyun Joo and Taehyeon Kim), has developed a one-dimensional (1D)–one-dimensional (1D) core–shell structured electrode material to overcome the poor stability of transition metal phosphides (TMPs) in alkaline electrolytes used in supercapacitors. This electrode features a structure in which transition metal oxides (TMOs) form a shell around TMP cores, effectively suppressing the oxidation of the core and thereby enhancing both structural stability and electrochemical performance. Furthermore, X-ray photoelectron spectroscopy (XPS) analysis and density functional theory (DFT) simulations revealed that the improved performance originates from electronic reconstruction at the core–shell interface. This research was published in the internationally renowned academic journal Small (Impact Factor: 12.1, Top 7.49%). The link: https://doi.org/10.1002/smll.202508090
