White Research Group - Electrochemistry
Electrochemical Methods, Nanobubbles, Electroorganic Synthesis, Bioanalytical Nanopore Analysis, Single Particle Techniques, Interfacial Kinetics and Electric Double Layer
The White group is an interdisciplinary team that applies electrochemical methods to advance the understanding of a variety of chemical, biological, and physical systems. Research topics currently include: single-molecule ionophoretic transport; nanopore analysis of biological particles; electrochemical scanned probe investigations; electrochemically generated nanobubbles; electroorganic synthesis; resistive-pulse sensing, and the role of the electric double layer on interfacial electron-transfer kinetics and molecular transport. See below for our latest publications, and the research section for more details on our research interests.
