Dynamic study of micro-domains on a phospholipid bilayer membrane

This paper presents experimental results of lateral phase separation on a multi-components membrane system, and the results together with data processing are discussed. In the experiments, phase separated domains show Brownian motion in the 2-dimensional system, thus an interaction between micro domains is calculated from a radial distribution function of domain distances. The measured interaction is sum of an excluded type repulsion in short range and a middle range attraction
