Research Interests

Atomic Spectroscopy

We develop "efficient" instrumental systems for Trace Element Analysis.  We explore ideas and optimize the performance by employing various spectroscopic theories, radiation and atom sources, sample introduction devices, and optical components.

Molecular Spectroscopy

We take advantage of and use the intense atomic emission available in high-energy electrical plasma, as the "self-tuned" radiation source for high-resolution molecular excitation.     

Single Molecule & Single Nano-particle Spectroscopy and Detection

We employ two systems:

 Microdroplet-levitation  -- a microdroplet, typically of 10 micrometer in diameter, is electrodynamically suspended in mid-air.  The single molecules or nano-particles in the droplet are laser-excited for detection and analysis.

Nano-stream  -- a slow-flowing narrow stream, typically of 3 micrometer in diameter, is electrically generated with a high voltage.  The single molecules or nano-particles in the probe -volume is laser-excited for detection.

Polymer Brush Synthesis

We wish to make and characterize a DNA-brush on glass substrate.  When long chain polymers are very close, with the end stick on substrate, they stand straight up in the z-orientation, resembling a "brush".

Nano-Particle Photonics

We synthesize dry single polymer molecules and single quantum (dots, rods, tubes, wires) particles in the z-orientation, on glass substrate.  The photonic properties of these solid particles have much improvement over those in solution or in other orientations.
