Abstract

We report on the phenomenology and kinetics of a self-spreading supported lipid bilayer (SLB) on a patterned surface. Analyses of our experiments provided two findings. One is that the self-spreading velocity increased when the SLB reached the inlet of the line patterns. This capillary effect-like behavior indicates an additional attractive interaction for SLB spreading in the line patterns. The other is that the front edge is always normal to the spreading direction even for curving lines. This can be attributed to the line tension at the spreading front edge.
