Vesicles of Toroidal Topology: Observed Morphology and Shape Transformations
Résumé
We report observations of toroidal vesicles with circular and noncircular cross sections, axisymmetric and nonaxisymmetric. Shape transformations induced by temperature changes are also described, which permit a connection to a mathematical conjecture due to Willmore. Our observations are analysed using a numerical procedure which allows a determination of the relevant geometrical parameters of the shapes. We compare these observations with recent theoretical predictions and point out some unexpected properties of the observed equilibrium shapes.
