ANALYTICAL CHEMISTRY

Our research efforts are focused on the development of plasmonic structures and nanoparticle assemblies with tunable optical properties and surface plasmon resonance-based sensing and spectroscopy platforms, particularly for biomolecule analysis. Our projects can be divided into three main areas:

Tunable plasmon-based sensing and spectroscopy platforms based on structural control and organized nanoparticle assembly Solution-based synthesis of metal nanoparticles using novel reducing agents that serve dual roles and provide additional control of materials properties Label-free, high-throughput bioassays based on surface plasmon resonance microscopy The broad nature of the multi-disciplinary research requires methods and tools from analytical chemistry, surface chemistry, biochemistry, materials science, nano\microfabrication, optics, spectroscopy, and microscopy. In addition to our focus on sensing and spectroscopy, our research will impact many areas of science and engineering using localized and propagating plasmons, including micro- and nano-scale device fabrication, nano-scale microscopy, nanolithography, solar energy conversion, and sensor development.
