Planting the seeds for nanoparticle growth

22-Apr-2009

Metal sulphide building blocks can be used to create functional heterostructured nanoparticles say scientists from Japan.

Toshiharu Teranishi and co-workers from the University of Tsukuba, Ibaraki, have developed a seed-mediated growth strategy to make flower- and dumbbell-shaped heterostructured nanoparticles. The group demonstrated that the resulting heterostructured nanoparticles consisted of metal sulphide building blocks.

The aim of the research was to find both ‘new heterostructured nanoparticles with interesting morphologies and to create the structure-specific novel functions of heterostructured nanoparticles.’ This work could provide a new mechanistic insight into the processes underlying formation of these nanoparticles says Teranishi.

Teranishi explains that there are still several challenges facing future research in this area, such as extending this method to enrich the heterostructured nanoparticle library, and being able to program the assembly of these nanoparticles by selective surface modification.

Teranishi’s group are currently studying the structure-specific functions of these new nanoparticles, including their self-assembly, and are applying this method to the synthesis of other heterostructured nanoparticles.

    Measuring the mass of molecules on the nano-scale

    Working with a device that slightly resembles a microscopically tiny tuning fork, researchers at the University of Tsukuba in Japan have recently developed coupled microcantilevers that can make mass measurements on the order of nanograms with only a 1 percent margin of error - potentially ... more

    Polymer films mimic nature’s iridescence

    Triple-layer photonic polymer films have been prepared that show the same type of iridescent optical behaviour that is seen in the bodies of some insects and birds. The scientists behind the work mimicked the phenomenon by preparing triple-layered films that contain different liquid crystal ... more
