A transmission electron microscopy image of a core–shell cubic nanoparticle. The new core-shell nanoparticles are highly versatile and are used in printing sensor arrays that measure levels of ...

They use the multilayer assembly approach to coat vascular stents with ultrathin films containing gold nanoparticles, barium sulphate and/or fluorescent-dye contrast agents, and demonstrate that ...

Further analysis in "dry" conditions revealed that the layer consists of spherical nanoparticles, each with sizes ranging from several tens of nanometers. TEM images taken at higher magnifications ...

More complex applications could depend on particular distributions of nanoparticles in a multilayer film, which could vary from layer to layer. This is needed for antireflection coatings ...
