Research

Our lab is applying modern analytical methods such as electrochemistry, spectroscopy and microscopy to multidisciplinary research. We specialize in the development and applications of scanning electrochemical microscopy (SECM), Raman microspectroscopy (RMS), atomic force microscopy (AFM), electrochemiluminescence (ECL), Chemiluminescence (CL) and Radioluminescence (RL) and their combination.

Chemical reaction imaging creates ways to visualize reactions of samples with their environments. For instance, SECM and RMS are being utilized in our group to unfold physiology and pathology of single live cells by mapping electron transfer, ion transfer, and molecule transfer such as reactive oxygen species across their membranes. Reactivities of grains and grain boundaries of Ti, Zr, and other materials are being determined and analyzed through these images on micrometer scale. AC-SECM has recently been combined with conventional DC-SECM in our lab to deconvolute the topography and chemistry profiles of specimens.

Chemical and electrochemical preparation of luminescent nanocrystals such as graphene quantum dots and electrochemical assembly of nanomaterials are actively pursued in our lab. ECL, and CL of various organic, inorganic molecules, polymers and various quantumdots and nanoclusters and the structure-property correlation are also being explored. These investigations will lead to advanced analytical methods such as spooling ECL spectroscopy, absolute luminescence quantum efficiencies and single ECL reactions as well as novel optoelectronic and photovoltaic devices.

Other research projects being carried out in our group include pharmaceutical analysis in biologic fluids, drug transfer, and ionic liquids with their reaction mechanisms and dynamics.
