Microcapsules: Delivery Systems for Low Molecular Weight Payloads: Core/Shell Capsules with Composite Coacervate/Polyurea Membranes (Adv. Mater. 23/2017)

In article number 1606099, Philipp Erni and co-workers report a strategy to form composite coacervate/polyurea capsules for the encapsulation of low-molecular-weight payloads, such as volatile fragrance molecules. A polyurea layer in the capsule shell provides a diffusion barrier in harsh media, whereas the protein-based coacervate component enhances adhesion on the targeted substrate.
