Adjust your lens of attention, and the world will whisper its secrets.


새로운 측정 및 분석 방법을 개발하여, 나노 세계 속 숨겨진 현상을 밝혀냅니다.
We develop new methods of measurement and analysis to reveal the hidden phenomena within the nanoscale world.

Single particle spectroscopy and imaging

- Luminescent nanoparticles including upconverting nanoparticles, quantum dots, plasmonic nanoparticles with emphasis on single-particle emission characteristics, phase behavior, and light–matter interaction at the nanoscale

- Laser particles exploring controllable optical switching and photonic functionalities at the single-particle level

- Heterogeneous nanostructures focusing on hybrid material platforms for enhanced emission and tailored photonic responses

Laser spectroscopy

- Fluorescence extended to biosensing and rapid molecular diagnostics

- Photoluminescence including emission control through plasmonic coupling and band-edge resonance engineering

- Surface-enhanced Raman scattering applied to nanoscale patterning, intracellular dynamics, and molecular identification

- Rayleigh scattering utilized for fundamental studies of nanoparticle optical properties and environmental particle analysis

Optical microscopy

- Super-resolution microscopy advancing correlative visualization of nanostructures beyond diffraction limits

- Live-cell imaging enabling real-time tracking of nanoparticle-mediated transport and intracellular processes

- In vivo imaging providing long-term monitoring of biodistribution and therapeutic pathways

Nanometrology

- Microscopy and spectroscopy for interfacial phenomena and capillary dynamics

- Correlative light-electron microscopy (CLEM) integrating multimodal characterization of nanoparticles, bioaerosols, and cellular interactions

Optical Diagnostics and Automated Photonic Systems

- High-precision optical techniques for diagnostics and measurement bridging nanoscale metrology with large-scale instrumentation

- Automated laser and optical platforms for stable, efficient operation developing self-aligning, feedback-controlled photonic systems

- Integration of photonics with automated control and data systems establishing real-time pipelines for measurement and analysis

- Applications to large-scale facilities and interdisciplinary research from plasma and isotope-beam diagnostics to biomedical and environmental monitoring
