We combine the fabrication of Au and Au/Ag core/shell nanorods (NRs), as well as experimental measurements of vis-NIR extinction, unpolarized, and cross-polarized light scattering spectra, with T-matrix and separation-of-variables simulations, to gain insight into the relation between the morphology/composition of nanoparticles and their isotropic and anisotropic optical responses. Using severa...

Arsenic poisoning from drinking water has been an important global issue in recent years. Because of the high level toxicity of arsenic to human health, an easy, inexpensive, low level and highly selective detection technique is of great importance to take any early precautions. This study reports the synthesis of Ag doped hollow CdS/ZnS bi-layer (Ag-h-CdS/ZnS) nanoparticles for the easy fluoro...

BACKGROUND Patients exposed to hepatitis C virus (HCV) may develop chronic infection with viremia. The diagnosis of this condition requires the use of several laboratory tests in algorithms tailored to the population and resources available for each laboratory. AIM We compared the diagnostic efficacy of two diagnostic algorithms for the identification of viremic patients with HCV. One based o...

Questions about how to regulate nanoenhanced products regularly arise as researchers determine possible nanoparticle transformation(s). Focusing concern on the incorporation and subsequent release of nano-Ag in fabrics often overshadows the fact that many "conventional silver" antimicrobials such as ionic silver, AgCl, metallic Ag, and other forms will also form different species of silver. In ...
