A material includes a layer with a plurality of self-assembled structures comprising compositions. The structures are localized in separate islands covering a portion of the layer in an integrated assembly. In some embodiments, the compositions include nanoparticles. In particular, some embodiments pertain to a material with a self-assembled formation of inorganic particles with an average diameter less than about 100 nm. The structures can be used as devices within an integrated article. The method for producing the articles comprise a localization process defining boundaries of the devices and a self-assembly process within the identified boundaries.

Self-assembled structures

Medical devices include biocomatible materials and a plurality of exogenous storage structures. The exogenous storage structures store a therapeutic agent which acts to inhibit restenosis. In some embodiments, the therapeutic agents are radioactive metal ions. In other embodiments, the medical device has an expandable structure with particles of therapeutic agent on its surface. The particles of therapeutic agent are delivered into a region susceptible to restenosis by direct application of the medical device against the adjacent wall.

Medical devices that resist restenosis

Polymer based solar cells incorporate nanoscale carbon particles as electron acceptors. The nanoscale carbon particles can be appropriate carbon blacks, especially modified laser black. Conducting polymers are used in the solar cells as electron donors upon absorption of light. Preferred solar cell structures involve corrugation of the donor/acceptor composite material such that increased amounts of electricity can be produced for a given overall area of the solar cell.
