Cover: Optically-adressable polymeric microshells made principally of poly(allylamine hydrochloride) and of an azobenzene-containing polyelectrolyte (PAzo) were produced using the layer-by-layer assembly technique. In water, these hollow containers are permeable to labeled polymers. However, by irradiating the loaded capsules with a light source of sufficient intensity, the former shrink and become impermeable to the dye. The supernatant may then be removed and the microshells along with their encapsulated material resuspended in water. Further details can be found in the article by M. Bédard,* A. G. Skirtach, G. B. Sukhorukov on page 1517.
