Abstract
In their Full Paper on page 201, Donald Martin and co‐workers describe the covering of polyelectrolyte microcapsules with a lipid bilayer that incorporates a novel engineered ion channel to provide a functional capability to control transport across the microcapsule wall. The cover image shows atomic‐force microscopy images of these 8‐layer polyelectroctrolyte capsules recorded using tapping mode in an aqueous environment. The capsules can be seen to collapse in a folded manner, with an occasional wrinkle that “absorbs” the extra surface area when flattening the spherical surface.
