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.
