Scanning Electrochemical Microscopy


We are investigating mechanisms for biofouling control at boron-doped diamond (BDD) electrode surfaces polarized at low applied potentials, using a model organism. We are also looking into the activation/inactivation of attahced bacteria at various applied electrode potentials. For this stuy, Scanning ElectroChemical Microscopy (SECM) provides near-surface pH and oxidant formation measurements under anodic and cathodic polarizations. For interpretation of SECM results, we are developing a transport model, which will allow us for a better understanding of the near-electrode chemistry.

coming soon!

Figure 1. Axisymmetric distribution of oxidant with high concentrataon near the BDD electrode (bottom, red) and low concentration near the SECM electrode tip (not pictured) at the top (blue) obtained by the transport-reactive model. Blue area on the right depicts the entry to the bulk with low concetration of the oxidant. Axis of symmetry is along the y-axis.
