Abstract: We investigated the kinetics of domain growth on liposomes caused by decreasing the temperature; the liposomes consisted of a ternary mixture (unsaturated phospholipid, saturated phospholipid, and cholesterol). The domain-growth process was monitored by fluorescence microscopy, and the growth was mediated by fusing the domains through collisions. It was found that an average domain size r develops with time t as r ~t^<0.15>. This indicates that the exponent is about half of that deduced from the theoretical analysis of a model of the Brownian motion on a two-dimensional membrane. We discuss the mechanism of the experimental scaling behavior by considering the elasticity of the membrane.
