Research
My research in the Baker Group focuses on the enhancement of chemically-sensitive scanning probes for scanning ion conductance microscopy (SICM)- an effort driven by the desire to increase the auxiliary information and analytical applications of SICM.
Several avenues including the development of ion-selective electrodes for SICM and bulk fabrication of parylene C insulated Au and pyrolyzed parylene C electrodes are being investigated.
Recently, we have developed a method to batch-fabricate scanning electrochemical- scanning ion conductance microscopy (SECM-SICM) electrodes. These probes have been utilized to investigate the flux of redox species through a nanopore and the changes in local concentrations can be switched "on" and "off" by altering the electrophoretic force.
Our future work will focus on additional applications of Au electrode/nanopipettes for the study of transport properties found in synthetic and biological materials, such as nanoporous polymer membranes, ion channels or intercellular tight junctions.
Background
In 2008, I graduated from Northern Kentucky University where I was fortunate to be involved in undergraduate research. Working with Prof. Keith Walters, I investigated synthetic routes toward fullerene-based molecular wires for solar cell applications.
