Abstract

Hydrogen-bonding layer-by-layer self-assembly has been successfully extended from two- to three-dimensional systems, i.e., to layers on spherical particles. Hollow capsules (see Figure) were prepared by subsequent removal of the sacrificial core. The core–shell particles and hollow capsules should find applications in medicine and biology.
