Research Statement
We are developing scanning probe microscopy (SPM) techniques that enable sensing, characterization, and actuation at the single molecule level. In particular, SPM-based nanolithography enables isolation of individual organic, biological, and inorganic molecules on semiconductor surfaces. The resulting nanostructures are employed in research topics ranging from fundamental studies of intermolecular phenomena to applied nanodevices. Ongoing materials science projects include exploration of molecular rotors, carbon nanotubes, catalytic oxide surfaces, ultrananocrystalline diamond, polymer micelles, and DNA/protein interactions. Concurrently, materials engineering projects are determining the suitability of surface-mounted nanostructures for molecular electronic devices, organic light emitting diodes, nanoscale gene chips, and biomedical nanosensors.
