Novel instrumentation

The research group lays claim to development of two novel SPR devices:

SPR sensing directly on a multimode optical fiber occurs in the region just below the 'N' on the dime.


The near-IR / mid-IR SPR platform is ideal for characterizing nanostructure arrays and explointing the enhanced sensitivity of SPR in the IR region.


Current Research

Our research interest is the development of in-situ chemical sensors for environmental, biomedical, and industrial process monitoring. Specifically, the research group has been concentrating on advancement of fiber optic surface plasmon resonance (SPR) Raman, and fluorescence sensors. In developing these sensors we meld instrumental design with advanced data analysis (Chemometrics) methods to achieve optimal instrumental performance. This research is driven by the realization that many measurement challenges – particularly problems involving analyte selectivity and sensitivity – are not best addressed by solely applying chemistry or physics solutions. These ‘physical’ solutions are often time, labor, and capital expensive. Instead, instrumental selectivity and sensitivity (and robustness) can often be enhanced by incorporating mathematical and statistical analysis of the collected data into the instrumental design.
