20_19/2008Cover Picture: Hierarchical Assembly of Multilayered Hollow Microspheres from an Amphiphilic Pharmaceutical Molecule of Azithromycin (Adv. Mater. 19/2008)

The cover represents a template-free method by hierarchical assembly of azithromycin molecules to form hollow microspheres with multilayered porous shells. Jian-Feng Chen, Lei Jiang, and co-workers report on p. 3682 this simple, rapid, and high-yielding method, which allows the number of layers to be tailored by regulating the initial concentration of the azithromycin solution. Such structures may find applications in controlled drug delivery, amongst other fields.
