We developed a novel electro-responsive drug delivery device by depositing fluorescein isothiocyanate (FITC)-loaded zinc oxide nanotubes (ZTs) onto indium tin oxide (ITO)/polyethylene terephthalate (PET) substrates (called FITC-ZTs-ITO/PET). With a large payload of FITC up to 0.98 mmol g(-1), the FITC-ZTs simultaneously provide a burst-like FITC release and a repeated step-like release after application of an electrical field at specific resonant frequencies. Additionally, FITC-ZTs-ITO/PET is biocompatible with both HeLa and MRC5 cells for ZT concentrations below 50 mu g/ml. These results demonstrate that FITC-ZTs-ITO/PET is a new platform that can provide local, on-demand electrically responsive drug release for biomedical applications.

Enhancement of light output intensity for GaN-based vertical light-emitting diodes (LEDs), combining wafer bonding and the laser lift-off (LLO) process, employing an omnidirectional extraction surface with synthesized single-crystal ZnO nanorod arrays in aqueous solution at room temperature is presented. The light output intensity and wall-plug efficiency of the GaN-based LLO vertical LED with the omnidirectional extraction surface by ZnO nanorod arrays shows 38.9 and 41.2% increases, respectively, at 200 mA current injections compared to that of a vertical LED without ZnO nanorod arrays. The ZnO nanorod arrays not only support a current spreading layer but enhance the probability of photon escape through the omnidirectional extraction surface. (C) 2008 The Electrochemical Society.

"The effect of pulsed laser annealing (PLA) on the photoluminescence (PL) properties of ZnO nanorods was investigated. As the fluence of pulsed laser increases, the UV PL in ZnO nanorods shows a general increasing trend, except at a range of fluences from 10 to 70?mJ/cm2. It is found that the treatment with the PLA at the fluence of 70?mJ/cm2 leads to a larger improvement of crystalline properties than that with rapid thermal annealing (RTA). The relationship between PL intensity and fluence of pulsed lasers can be well explained by a combination of the deterioration in surface crystallinity and the increased donor densities after PLA."
