research - electrochemistry
Our group is focused on all things electrochemical. Fundamentals, applications, instrumentation. Some recent areas of interest are shown below. Highlights below are examples of our work, the full scope is much wider, please browse our publications for a full view.
Scanning Ion Conductance Microscopy
We have been interested in electrochemical applications of scanning ion conductance microscopy (SICM) for the last fifteen years. SICM provides quick and straightforward access to nanoscale electrochemical measurements and can be integrated with many different areas of study. We recently chronicled the history of SICM, including our work, and postulated on future applications of SICM (Chemical Reviews, 2020).
Developing new tools for electrochemical measurements at small scales is a driving force in our research. Instrumentation is focused on new concepts in measurement and applications toward meaningful chemical/biochemical/materials measurements. An example of this is the Array Microcell Method (AMCM) which we recently described (ChemElectroChem, 2020). We also frequently add to the arsenal of applications and tools related to SICM. We are also interested in applicaitons of scanning electrochemical cell microscopy and scanning electrochemical microscopy.
Surface Charge Measurements with SICM
Surface charge is an incredibly important aspect of interfacial reactivity and recognition and is an intrinsic feature of most electrochemical systems. We have developed and continue to explore instrumentation and experiments to transduce surface charge with scanning ion conductance microscopy (SICM). (ChemElectroChem, 2018).
The Intersection of Electrochemistry and Mass Spectrometry
The application of nanopipettes, developed first as a tool for electrochemistry and electrophysiology, as tools for mass spectrometry are an area of interest. Recent examples from our lab include advances in electrospray ionization and sampling for mass spectrometry with nanopipettes, areas we continue to explore. Our work and this area are discussed in a recent opinion piece. (Current Opinion in Electrochemistry, 2019).
