Metal Capsules: Nanoengineered Metal Surface Capsules: Construction of a Metal‐Protection System (Small 6/2012)

A sonodesigned metal-based sponge can form as a surface layer on metal capsules with the possibility of multicomponent loading and time-resolved release. The capsules can be loaded with active agents, such as corrosion inhibitors, vitamins and drugs, enzymes, DNA fragments, or antibodies. The porous layer is continuous with the bulk metal allowing for excellent double-side adhesion during the construction of a feedback (anticorrosion, biocide) coating. This system could potentially be used to develop new medical therapies, such as laboratory organ/tissue growth for human transplants.
