Researchers in Germany managed to integrate quantum dots (QD) into the walls of nano- and microtubes. This novel structure serves as a quantum light emitter as well as optical waveguide. This represents a major step toward the realization of flexible high quality factor optical resonators based on tubes.

Polymeric hollow nanospheres with high stability and controllable permeability have interesting potential applications associated with the controlled release of encapsulated active ingredients (e.g., drugs, vaccines, antibodies, hormones, pesticides, and fragrances) under well-defined conditions. Researchers in Singapore are now fabricating hollow nanostructures with different shapes using a single template.

A group of Chinese researchers prepared dye-sensitized solar cells using micro/nanocomposite TiO2 porous films, resulting in cells with enhanced light collection. They applied a technique which can produce a large area in continuous fabrication. This technique opens an alternative way for manufacturing solar cells on an industrial scale.
