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.

    New molecular probes that shed light on biological systems

    Reactive sulfur species have attracted increasing attention in biomedical research because of their involvement in a variety of physiological functions. There has been a rising interest in sulfane sulfur compounds – compounds which contain sulfur atoms with six valence electrons, but no cha ... more

    Driving magnesium micromotors with seawater

    Scientists in the California have developed magnesium-based Janus micromotors that self-propel in seawater. Research shows how the micromotors can be used to capture and transport oil droplets from contaminated seawater, presenting a possible environmental application for the removal of oil ... more

    Moving liquid metal marbles

    Researchers in Australia have found a new method to induce the controlled movement of liquid metal droplets in aqueous environments, by coating them in nanoparticles to form ‘liquid metal marbles.’ Research shows that coating droplets of liquid metal galinstan with WO3 nanoparticles increas ... 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
