Interfacial chemistry, ultrathin organic films, and scanning probe microscopy
|Our research focuses on atomic force microscopy (AFM) investigations of the structure/interfacial property relationships of ultrathin organic films (self-assembled monolayers, supported phospholipid films,
polyelectrolytes). An understanding of how the two-dimensional organization and defect structure of these films determine their redox properties and surface interactions is key to the engineering of functional surfaces for molecular electronic devices,
biomimetic surfaces, and the development of chemically-sensitive AFM techniques.|
Ongoing projects include:
1. AFM studies of the phase behavior of supported lipid membranes
2. Design of nanostructured phospholipid films and their use as selective adsorption templates
3. Electrochemical modulation of adhesion forces in AFM
4. Surface stress measurements of redox-active thin films using an AFM microcantilever sensor
Students undertaking any of these projects will gain experience in surface and interfacial chemistry, organic thin film preparation methods (self-assembly and Langmuir-Blodgett technique), scanning probe microscopy, electrochemical methods, and surface plasmon resonance spectroscopy.
