Dynamic Behavior of Lipid across a Micropore during Self-Excited Potential Oscillation

Abstract
This letter reports observation with an optical microscope on dynamic behavior of a lipid across the oil/water interface, which are formed at a micropore of 2 µm in diameter during self-excited potential oscillation. Periodical movement of dome-shaped body on the interface is observed, and its expansion and shrinkage are quite synchronous with the potential oscillation.
