Many chemical and biological processes depend on electrons or ions moving across a surface. Examples include signaling between neurons, wound healing in skin-like cell layers, and reactions on catalyst particles.

What they work on
- Build Optically Guided Nanoscale Electrochemical Imaging (OG-NEI), hardware and protocols that combine scanned-probe electrochemical imaging with bright field, dark field and fluorescence optical imaging at the same time.
- Integrate OG-NEI into scanning electrochemical microscopy, scanning electrochemical cell microscopy and scanning ion conductance microscopy, and measure gains in data collection and high-throughput measurement.
- Develop statistical and machine learning methods to align and analyze data from complementary optical and electrochemical imaging modes.
- Apply the platform to neuronal cells, epithelial cell monolayers, and single- and multi-metal nanoparticle catalysts to study chemical and electrochemical processes at the nanoscale.
More about the research
These events happen at the scale of nanometers, billionths of a meter, which is much smaller than most chemical measurements can resolve. Probe-based electrochemical microscopes can map such activity in fine detail, but it is hard to know exactly where on a sample the probe is measuring. This project aims to solve that by combining electrochemical imaging with ordinary light microscopy, so researchers can see a sample and measure its chemistry at the same time.
Why it matters
Better nanoscale chemical imaging could help researchers understand how neurons communicate and how wounds heal, knowledge that could eventually inform efforts to treat disease. Mapping reactions on single metal nanoparticles may also guide the design of more efficient and selective catalysts for energy and materials applications. A shared, general imaging platform would give other electrochemistry labs these capabilities.
Known grants
