Professor Seung Wook Kim's research lab specializes in the development of advanced biomaterials and nanomaterials for biomedical and energy applications. The lab focuses on creating smart, skin-integrated microfluidic systems for real-time sweat analysis, exploring the pathophysiology of bone diseases using stem cell models, and investigating cellular signaling mechanisms in cancer. Additionally, the lab pioneers the synthesis of novel perovskite nanowires with unique crystal phases for high-performance energy-harvesting devices. These interdisciplinary efforts bridge materials science, bioengineering, and molecular biology to address challenges in personalized medicine and sustainable energy.

This paper introduces super absorbent polymer valves and colorimetric sensing reagents as enabling components of soft, skin-mounted microfluidic devices designed to capture, store, and chemically analyze sweat released from eccrine glands. The valving technology enables robust means for guiding the flow of sweat from an inlet location into a collection of isolated reservoirs, in a well-defined sequence. Analysis in these reservoirs involves a color responsive indicator of chloride concentration
We postulated that osteogenic and adipogenic differentiation ability of the mesenchymal stem cells isolated from the bone marrow could be altered in patients with alcohol-induced osteonecrosis of the femoral head. To examine this hypothesis, we investigated the differentiation ability of the mesenchymal stem cells isolated from the bone marrow from the proximal end of the femur during hip replacements in patients with alcohol-induced osteonecrosis of the femoral head and compared it with the dif
Bidirectional signaling between astrocytes and cancer cells involves upregulation and activation of the endothelin axis, which protects cancer cells from cytotoxicity induced by chemotherapeutic drugs.
Annexins (ANXs) display regulatory functions in diverse cellular processes, including inflammation, immune suppression, and membrane fusion. However, the exact biological functions of ANXs still remain obscure. Inhibition of phospholipase A(2) (PLA(2)) by ANX-I, a 346-amino acid protein, has been observed in studies with various forms of PLA(2). "Substrate depletion" and "specific interaction" have been proposed for the mechanism of PLA(2) inhibition by ANX-I. Previously, we proposed a specific
We report the synthesis of KNbO(3) nanowires (NWs) with a monoclinic phase, a phase not observed in bulk KNbO(3) materials. The monoclinic NWs can be synthesized via a hydrothermal method using metallic Nb as a precursor. The NWs are metastable, and thermal treatment at ∼450 °C changed the monoclinic phase into the orthorhombic phase, which is the most stable phase of KNbO(3) at room temperature. Furthermore, we fabricated energy-harvesting nanogenerators by vertically aligning the NWs on SrTiO(
