Antiviral Activity of Zinc Oxide Nanoparticles and Tetrapods Against the Hepatitis E and Hepatitis C Viruses.

Hepatitis E virus (HEV) causes an acute, self-limiting hepatitis. The disease takes a severe form in pregnant women, leading to around 30% mortality. Zinc is an essential micronutrient that plays a crucial role in multiple cellular processes.

A facile, viable approach toward the preparation of 32p patches for the treatment of skin cancer.

A facile, viable, "green" two-step, inexpensive technique was developed for the preparation of (32)P patch for the treatment of skin cancer. This technique consists of impregnation of H(3)(32)PO(4) solution into an inert solid carrier followed by immobilization into a nonleachable matrix by lamination. The morphology of the impregnated paper was evaluated by scanning electron microscope and energy-dispersive spectral analyses.

Tellurium nano-structure based NO gas sensor.

Tellurium nanotubes were grown on bare and silver/gold nanoparticle (nucleation centers) deposited silicon substrates by vacuum deposition technique at a substrate temperature of 100 degrees C under high vacuum conditions. Silver and gold nanoparticles prepared on (111) oriented silicon substrates were found to act as nucleation centers for growth of Tellurium nanostructures. Density of nanotubes was found to increase while their diameter reduced when grown using metallic nanoparticle template.

Chlorine gas sensors using one-dimensional tellurium nanostructures.

Tellurium nanotubes have been grown by physical vapor deposition under inert environment at atmospheric pressure as well as under vacuum conditions. Different techniques such as scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD) and optical absorption have been utilized for characterization of grown structures. Films prepared using both types of tellurium nanotubes were characterized for sensitivity to oxidizing and reducing gases and it was found that the relative response to gases depends on the microstructure.

Development of a spherical (125)i-brachytherapy seed for its application in the treatment of eye and prostate cancer.

Palladium-coated silver beads of 0.5 mm (phi) were used to adsorb (125)I, encapsulated inside a titanium capsule by an Nd:YAG laser, for use as a brachytherapy source. Experimental conditions, such as feed activity, carrier concentration, and reaction time, were optimized for the maximum adsorption of (125)I.
