Scanning tunneling microscopy and spectroscopy at 5 K have been used to determine the electronic properties of 7-nm dodecanethiol-passivated Au nanocrystals in three different configurations: isolated nanocrystal, self-organized thin films (few nanocrystal layers), and large three-dimensional well-defined thick films (over 30 nanocrystal layers) called supracrystals. The electronic properties of both thin and thick well-ordered supracrystals are analyzed in scanning tunneling spectroscopy…

Gold nanoparticles have been increasingly used in medicine lately to diagnose and treat diseases. However, researchers keep arguing their possible toxicity and ability to cause mutations. Experts at Razumovsky Saratov State Medical University; and the Institute of Biochemistry and Physiology of Plants and Microorganisms, Russian Academy of…

Recently, word has been appearing in scientific literature suggesting that collaurin can activate the immune system response to foreign antigens. Researchers at the Institute of Biochemistry and Physiology of Plants and Microorganisms, Russian Academy of Sciences, and the State Scientific Institution of Saratov Research Veterinary Station of Russian Agriculture Academy; have proved that gold nanoparticles increase…
