Fabrication and characterization of well-aligned, high density ZnO nanowire arrays and their realizations in Schottky device applications using a two-step approach: A two-step approach for preparing a large area array of high density and horizontally well-aligned of zinc oxide nanowires, has been developed by German and Chinese scientists. The team claim that these arrays are suitable for preparing Schottky diodes on inexpensive and flexible polymer substrates. (J. Mater. Chem., 2011, 21, 7090-7097)
TAT-conjugated nanodiamond for the enhanced delivery of doxorubicin: The anticancer drug doxorubicin and cell penetrating peptide TAT were conjugated to the surface of nanodiamonds. The conjugate is designed to avoid premature release and enhance the intracellular delivery of the drug. The team says that conjugation of TAT to nanodiamond–doxorubicin increases the cytotoxicity of doxorubicin compared to the free drug. (J. Mater. Chem., 2011, DOI: 10.1039/C1JM10653H, Advance Article)
Flower-like hydroxyapatite modified carbon paste electrodes applicable for highly sensitive detection of heavy metal ions: A team of scientists based in China and the UK have created a highly sensitive sensor for the detection of Pb2+ and Cd2+ ions. The sensor uses flower-like hydroxyapatite crystals fabricated on egg-shell membranes as modifiers for a chemically modified carbon paste electrode. (J. Mater.
