▪️ Plasmonic nanostructures & Surface-Enhanced Raman Scattering (SERS)

Our group focuses on the synthesis, design, and optimization of plasmonic metallic nanoparticles. By precisely controlling plasmonic nanogaps through the optical properties of nanoparticles, maximization of signal amplification. SERS to amplify the Raman signals of absorbed molecules. Furthermore, by comparing the SERS signals of internal standards and target molecules, we establish a system that allows simple yet highly accurate quantitative analysis. Based on this approach, we are developing high sensitivity and high reproducibility analytical platforms, which can be extened to a wide range of applications.

▪️ Quantum Dots for Biomedical Applications

In the biomedical field, quantum dots (QDs) demonstrate 10-100 times higher brightness and stability than conventional fluorophores and allow the simultaneous detection of multiple targets. Our group develops QD-based nanostructures for high-sensitivity bioimaging and early diagnosis, with strong potential in therapeutic discovery and new drug development. Building on this foundation, we strive to pioneer highly sensitive biomolecular detection materials and next-generation diagnostic kit technologies.
