摘要
(Figure Presented) Escape route: The laser-initiated release of fluorescently labeled polymers from polyelectrolyte-multilayer microcapsules is demonstrated inside living cancer cells. A polymer is incorporated in capsules with metal nanoparticles in their walls, which serve as light-absorbing centers. The capsules are internalized by cells and near-infrared light ruptures the walls of the capsules, thus releasing the content into the cells. © 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
