The Schwartz group pursues fundamental and application-driven research involving the interactions between molecular adsorbates and surfaces with a particular emphasis on molecular self-organization, biotechnology, nanoscience, catalysis, and single-molecule tracking methods at “wet” interfaces. The direct observation of dynamic molecular behavior at the single-molecule level permits the characterization of heterogeneous interfacial behavior in ways that are inaccessible to traditional ensemble-averaging methods1. In other research, we use liquid crystals (LCs) to detect specific interactions associated with nucleic acids for applications in nucleic-acid based biodetection2. Finally, recent work in collaboration with the Medlin group, we have pursued research involving the effects of thiolate self-assembled monolayers (SAMs) on supported metal catalysts. Surprisingly, SAM-coated catalysts exhibit greatly modified selectivity for the hydrogenation of multifunctional reactants.
