Axisymmetric colloidal membranes


Colloidal membranes are highly replicable, microscopic structures with potential applications in drug delivery. Recent experiments reveal that these membranes can assume catenoidal shapes similar to that of a soap film between two rings. We theoretically determine the shapes of more complex membranes by generalizing the soap-film model to include membrane bending stiffness and Gaussian curvature modulus. Our findings indicate the existence of catenoid-like shapes under the boundary condition of vanishing bending torque, and the physical constants introduced from this condition can be varied to form shapes distinct from the basic catenoid solution.
