Observation of nanoimpact events of catalase on diamond ultramicroelectrodes by direct electron transfer

Author affiliations

Abstract

We report electrochemical detection of single-catalase collisions at diamond ultramicroelectrodes and show the operative mechanism involves direct enzyme-mediated charge transfer between electrode and solution. Hydrogen peroxide increases the collision frequency, which fluorescence correlation spectroscopy diffusion measurements suggest stems from an increase in the diffusion rate as the underlying cause.
