Understanding the Local Chemical Environment of Bioelectrocatalysis [PDF]

Proceedings of the National Academy of Sciences, 2021
This work applies electrochemical and computational techniques to explore the local environment of fuel-producing oxidoreductases within porous electrode architectures. This improved understanding of the local environment enabled simple manipulation of the electrolyte solution, by adjusting the bulk pH and buffer pKa, to achieve an optimum local pH for
