Im defends PhD thesis on novel chemical sensing materials

On September 2, 2011, JiSun Im successfully defended her doctoral dissertation in the Department of Chemistry, entitled “Chemiresistors based on thiol-functionalized gold nanoparticles, metal oxides, and their composites for the detection of toxic chemicals.”

Dr. Im’s research was conducted under the supervision of Professor James Whitten. With funding from the Army Research Laboratory, her work focused on developing chemical sensing materials for the detection of toxic chemicals, including volatile organic compounds, explosives, and nerve agents.

During her five-year graduate career at UMass Lowell, Im spearheaded the development of a portable prototype sensor system, nicknamed the “Mini-Mutt.” This instrument uses nano-particles and electrically conducting polymers to detect and identify chemical vapors. A video story about the Mini-Mutt is presently online at

Dr. Im has accepted a postdoctoral research position at the Massachusetts Institute of Technology.
