Thickness dependence of the crystallization of Au/glass ultrathin films.

Tae-Sik Cho et al.

Journal of nanoscience and nanotechnology, 13(5), 3711-3714 (2013-07-19)

The crystallization of Au/glass ultrathin films for surface plasmon resonance (SPR) biosensor has been studied using synchrotron X-ray scattering and field emission scanning electron microscope. In films thinner than 30 nm, crystallized Au grains with [111] preferred orientation were formed

Cytotoxicity and genotoxicity induced by photothermal effects of colloidal gold nanorods.

Young Joo Choi et al.

Journal of nanoscience and nanotechnology, 13(6), 4437-4445 (2013-07-19)

Gold nanorods (Au NRs) that absorb near-infrared (NIR) light have great potential in the field of nanomedicine. Photothermal therapy (PTT), a very attractive cancer therapy in nanomedicine, combines nanomaterials and light. The aim of this study was to elucidate the

Engineering bioconjugated gold nanospheres and gold nanorods as label-free plasmon scattering probes for ultrasensitive multiplex dark-field imaging of cancer cells.

Tianxun Gong et al.

Journal of biomedical nanotechnology, 9(6), 985-991 (2013-07-19)

In this paper, we proposed the use of gold nanoparticles as plasmon scattering probes for dark-field multiplex imaging of live cancer cells. By carefully engineering the surfaces, aqueous dispersions of anti-EGFR antibody-conjugated gold nanospheres and gold nanorods are prepared. We
