Data from Institute of Intelligent Machines Provide New Insights into Nanoparticles

June 20, 2014

By a News Reporter-Staff News Editor at Health & Medicine Week -- Researchers detail new data in Nanoparticles. According to news reporting from Hefei, People's Republic of China, by NewsRx journalists, research stated, "The L-cysteine molecules were successfully grafted to the 2-amino group of chitosan by a reactive amine reduction, and the as-synthesized thiolated chitosan (TC) molecules were used as the templates to direct the self-assembly of gold nanoparticles and induce the transformation of these assemblies to gold microcubes through a deep-going dialysis. We found that the ratio of gold nanoparticles to TC molecules could greatly affect the shape of the assembled clusters."

The news correspondents obtained a quote from the research from the Institute of Intelligent Machines, "Different stages of these clusters and microstructures during the dialysis process were characterized by scanning electron microscope (SEM), and the microcubes with average side length of about 20 mu m were successfully synthesized. According to the morphology evolution of the assembly, it could be concluded that the microcubes were formed from external to internal. The SERS area mapping images of microcubes and some clusters were also collected to study the formation mechanism of gold microcubes."

According to the news reporters, the research concluded: "Our work demonstrates a simple and highly effective way to assemble gold nanoparticles into microcubes with unique properties."
