This paper shows that AC electro-osmosis causes fluorescent dips in cationic fluorophores, creating false action potential signals in bacterial cells and biofilms.

The paper models electrical signaling in E. coli biofilms using a fire-diffuse-fire model, showing that wavefronts exhibit super-diffusive scaling and are influenced by geometry and ion diffusivity.

The paper demonstrates that E. coli biofilms exhibit negative capacitance at low frequencies in electrical impedance spectroscopy, similar to neuronal behavior, and links this to voltage-gated potassium channels.
