Imitating nature : The authors attempted to assemble lipids on polyelectrolyte (PE) capsules (see graphic) to reduce the permeability of the capsules towards ions and small neutral molecules, thus imitating the barrier function of biological membranes. The lipid may form bilayer structures on the capsule surface, which provides the possibility to incorporate membrane‐specific components such as channels and receptors for specific permeation and recognition.
