Perturbative analysis shows membrane capacitance dynamics influence potential changes during ion activity.

This research investigates the timescales of capacitive response in biological membranes under electric fields.
Used a minimal model of a biological membrane subject to a step voltage.
Performed a perturbative analysis of electrolyte transport equations.
Estimated capacitive timescales and compared them with classic experiments.
Found that capacitive timescales are significantly shorter than traditional RC timescales.
Demonstrated that these timescales are crucial for understanding potential dynamics during ion channel activity.
Identified a nonlinear relaxation process driven by salt diffusion.

Farhadi et al. (2026) studied this question.
