Abstract

This research project is focused on the preparation and characterization of nanoelectrodes for biosensing applications and exploration of nanoelectrode based nanoparticle for single molecule electrochemistry. Nanoelectrodes will also be used as probes in Scanning Electrochemical Microscopy (SECM) for understanding electron-transfer kinetics, probing single catalytic nanoparticles and to nanoscale electrochemical imaging.
