Query: Force induced formation of twisted chiral ribbons   We study the emergence of helical structures subjected to a stretching force,
demonstrating that the force transforms disk-shaped colloidal membranes into
twisted chiral ribbons of predetermined handedness. Using an experimental
technique that enforces torque-free boundary conditions we simultaneously
measure the force-extension curve and quantify the shape of emergent ribbons.
An effective theory that accounts for the membrane bending energy and uses
geometric properties of the edge to model the internal liquid crystalline
degrees of freedom explains both the measured force-extension curve and shape
of the twisted ribbons in response to an applied force.
