Nanostructured colloidal systems inspired by nature

Recent work on bioinspired nanoscale colloidal systems is an example of the significant interest that the design and fabrication of nanostructured colloidal materials has created among scientists.

Creating differently shaped and sized hollow nanospheres from a single template

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.

Micro/nano composite structure enhances performance of solar cells

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.

Electrochemical probes with nanometer dimensions

Researchers in Finland and The Netherlands demonstrated that it is possible to grow and wire a single platinum nanoparticle using a single-walled carbon nanotube, thus providing a bottom-up approach to building nanoelectrodes.

Carbon/copper nanocomposites as novel, low-cost sensor materials

Researchers in Switzerland succeeded in the large-scale production of carbon-coated copper nanoparticles. These carbon/copper nanocomposites could be used as novel, low-cost sensor materials and offer a metal-based alternative to the currently used brittle oxidic spinels or perovskites.
