We carry out Monte Carlo simulations of a colloidal fluid membrane composedof chiral rod-like viruses. The membrane is modeled by a triangular mesh ofbeads connected by bonds in which the bonds and beads are free to move at eachMonte Carlo step. Since the constituent viruses are experimentally observed totwist only near the membrane edge, we use an effective energy that favors aparticular sign of the geodesic torsion of the edge. The effective energy alsoincludes membrane bending stiffness, edge bending stiffness, and edge tension.We find three classes of membrane shapes resulting from the competition of thevarious terms in the free energy: branched shapes, chiral disks, and vesicles.Increasing the edge bending stiffness smooths the membrane edge, leading tocorrelations among the membrane normal at different points along the edge. Wealso consider membrane shapes under an external force by fixing the distancebetween two ends of the membrane, and find the shape for increasing values ofthe distance between the two ends. As the distance increases, the membranetwists into a ribbon, with the force eventually reaching a plateau.
