New Nanocomposites Findings Reported from E. Vasile and Co-Authors

May 20, 2014



By a News Reporter-Staff News Editor at Life Science Weekly -- Current study results on Nanocomposites have been published. According to news reporting originating from Bucharest, Romania, by NewsRx correspondents, research stated, "Gold-dendrimer nanocomposites were obtained for the first time by a simple colloidal approach based on the use of polyamidoamine dendrimers with succinamic acid terminal groups and dodecanediamine core. Spherical and highly crystalline nanoparticles with dimensions between 3?nm and 60?nm, and size-polydispersity depending on the synthesis conditions, have been generated."

Our news editors obtained a quote from the research, "The influence of the stoichiometric ratio and the structural and architectural features of the dendrimers on the properties of the nanocomposites has been described. The self-assembling behaviour of these materials produces gold-dendrimer nanostructured porous networks with variable density, porosity, and composition. The investigations of the reaction systems, by TEM, at two postsynthesis moments, allowed to preliminary establish the control over the properties of the nanocomposite products. Furthermore, this study allowed better understanding of the mechanism of nanocomposite generation. Impressively, in the early stages of the synthesis, the organization of gold inside the dendrimer molecules has been evidenced by micrographs. Growth and ripening mechanisms further lead to nanoparticles with typical characteristics."

According to the news editors, the research concluded: "The potential of such nanocomposite particles to induce calcification when coating a polymer substrate was also investigated."
