Left-handed, coiled, 4,4′-biphenylene bridged polybissilsesquioxane, tubular nanoribbons were prepared according to the published literature. After carbonization and removal of silica using HF aqueous solution, left-handed, coiled, carbonaceous, tubular nanoribbons were obtained. The left-handed, coiled, carbonaceous, tubular nanoribbons were characterized using field-emission scanning electron microscopy,...
Single-handed helical silica nanotubes were prepared according to the literature procedures, using the self-assemblies of a pair of chiral cationic low-molecular-weight gelators as the templates. A chirality indicator, 4,4′-bis(triethoxysilyl)-1,1′-biphenyl, was developed to determine the chirality of the silica nanotubes. The chirality of the surfaces and the bulky walls of the silica nanotubes were...
Nanoparticles containing the infrared-to-visible up-converting phosphors (UCP) ytterbium and erbium and co-doped with sodium yttrium fluoride were synthesized with diameters ranging from 30 nm to 50 nm. These high luminescence efficient UCP beads were employed as detection labels and applied in microarrays for the detection of specific nucleic acid hybrids to identify bacteria for the first time....
