Research Interests

Tip-Enhanced Raman Scattering (TERS)
TERS was named and first reported by Prof. Suh and coworkers in Jan. 2000, now cited up to ~1,500 times. For the last two decades, TERS has been developed to provide Single Molecule Detection (SMD) sensitivity and sub-angstrom level Raman imaging at cryogenic temperature in UHV condition. We are now developing SMD by TERS operating in ambient condition to expand its applicability.

Nanogap-Enhanced Raman Scattering (NERS)
Prof. Suh’s research group has pioneered NERS with SMD sensitivity, another new research area of Nano Raman. Our two pioneering reports of NERS in Nature Materials (2010) and Nature Nanotech (2011) have already been cited for the past decade up to ~1,050 and ~900, respectively. We are now making efforts to apply NERS for in vitro diagnosis (IVD).

UpConverting Nano Particle (UCNP)
The first single-particle UCNP spectroscopic imaging experiments were independently reported by Prof. Suh’s group and by Prof. P. J. Schuck’s group in 2009. Since then Prof. Suh’s group have been applying UCNP to single-particle-tracking live-cell imaging, small animal imaging, and super-resolution nanoscopy. Recently, Prof. Suh, together with Prof. Schuck, has created the first UCNP Gordon Research Conference(GRC), which will be held in June 2021 at New Hampshire, U.S.A.
