Nanoelectrochemistry refers to a range of applications that operate on the nano-scale. Part of this field are the investigation of nanoparticles or other nanostructured materials, but also single-entity electrochemistry or single molecule detection. The development of nanoelectrodes and measuring systems which can detect currents in the lower pA range are the prerequisites for this field of research.
Nanoelectrodes enable the investigation of the nucleation process of nanobubbles at the electrode surface which are formed in an electrochemical reaction. Apart from the fundamental interest to understand the mechanism of nanobubble formation, bubble formation has been implied to have a significant impact on the electrocatalytic activity of nanoparticles and on gas transport propertiesin fuel cells.
