چکیده

Herein we demonstrate that intrinsically fluorescent zinc oxide (ZnO) nanowires (NWs) can be adopted for molecularly targeted imaging of cancer cells, after they are functionalized to render water solubility, biocompatibility, and low cellular toxicity. Optical imaging of integrin α(v)β(3) on U87MG human glioblastoma cells was achieved with RGD peptide-conjugated green fluorescent ZnO NWs, which opened up new avenues of research for investigating ZnO NW-based agents in tumor vasculature-targeted molecular imaging and drug delivery.

The study of humidity effect on carbon dioxide gas sensing properties of zinc oxide nanowires assisted by polyvinyl alcohol network at room temperature

In this research, Zinc oxide (ZnO) nanostructures were synthesized by low cost hydrothermal method. The grown ZnO nanostructures had a dispersed distribution with nanowire morphology and the specific surface area of about 7 m2.gr-1 which they have crystalized in hexagonal wurtzite structure. ZnO nanowires/polyvinyl alcohol network (ZP) on the epoxy glass substrate with cu-interdigited electrods...

Room-temperature ultraviolet nanowire nanolasers.

Room-temperature ultraviolet lasing in semiconductor nanowire arrays has been demonstrated. The self-organized, <0001> oriented zinc oxide nanowires grown on sapphire substrates were synthesized with a simple vapor transport and condensation process. These wide band-gap semiconductor nanowires form natural laser cavities with diameters varying from 20 to 150 nanometers and lengths up to 10 micr...

Study of structural, optical and electrical properties of ZnO/CuO nanocomposites

In this work, the first ZnO/CuO nanocomposites were synthesized by chemical vapour deposition (CVD), thermal evaporation (PVD) and sputtering on silicon substrates (Si). Then, the structural, optical and electrical properties of the samples were investigated. Examination of the X-ray diffraction patterns confirmed the mixed-phase formation of hexagonal zinc oxide (ZnO) and monoclinic copper oxi...
