Our group is interested in the use of molecular recognition for chemical sensing. On one hand, we develop chemical sensors for clinical and environmental applications. Our research focuses on new receptors that bind analytes of interest with high selectivity, novel strategies to obtain very low detection limits, and perfluoropolymers that permit long-term monitoring and eventually the implantation into the human body. On the other hand, we chemically modify metal and carbon nanotube tips, and use them in scanning tunneling microscopy for chemically selective imaging with molecular resolution.
