22-04-2009: 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.
