In Situ Spectroelectrochemical Investigation of Electrocatalytic Microbial Biofilms by Surface‐Enhanced Resonance Raman Spectroscopy

A mixed-culture-derived microbial biofilm, grown on silver electrodes, was studied in vivo with surface-enhanced resonance Raman scattering (SERRS) in combination with cyclic voltammetry. This experimental approach provides unprecedented structural information about the outer membrane cytochromes involved in the direct electron transfer across the bacterium–electrode interface.
