Glucose oxidase (GOD)-catalyzed electron transfers between some oxidants in nitrobenzene (NB) and glucose in water (W) were studied by cyclic voltammetry. When an electrically neutral compound, chloranil (CQ), was employed as the oxidant in NB, the enzymatic reaction could not be regulated because of the spontaneous transfer of CQ from NB to W. In this case, the voltammetric wave observed for the enzyme-catalyzed electron transfer was increased depending on the standing time until the voltage scan was started. However, when an ionic oxidant, dimethylferricenium ion (DiMFc+), was employed as the oxidant, the electrochemical control of the enzymatic reaction was achieved by controlling the interfacial transfer of DiMFc+, so that well-reproducible voltammograms could be obtained for different concentrations of DiMFc+ and for different scan rates. The voltammetric behaviors were successfully explained by a digital simulation based on the ion-transfer mechanism, which involves the interfacial transfer of DiMFc+ and the succeeding GOD-catalyzed electron transfer which occurs not heterogeneously at the interface, but homogeneously in the W phase.

Physical Chemistry Chemical Physics

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
