Free trade : The electron exchange of cytochrome c freely diffusing to gold electrodes modified by hydroxy‐terminated alkanethiol self‐assembled monolayers (SAMs; see picture) is examined by high‐pressure kinetic studies. The SAM thickness, solution viscosity, and hydrostatic pressure influence a changeover in the charge‐transfer mechanism and the corresponding kinetic response.
