Comparative Study of Larvicidal Activity of Spinel CoO Nanorods and Entomopathogenic Conidia against .

Herein, we report the synthesis of spinel cobalt oxide nanorods (CoO NRs) by a modified co-precipitation approach and examine their larvicidal activity against The structure and morphology of the as-prepared CoO NRs were emphasized using X-ray diffraction (XRD), Raman spectroscopy, energy dispersive X-ray spectroscopy (EDAX), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). It was found that CoO nanostructures have a face-centered spinel cubic crystal structure with a mean crystallite size of 38 nm. These nanostructures have a rod like shape with a mean diameter of 30 nm and an average length of 60 nm.

Nanoparticles as a novel and promising antiviral platform in veterinary medicine.

Traditional veterinary virus vaccines, such as inactivated and live-attenuated vaccines, have achieved tremendous success in controlling many viral diseases of livestock and chickens worldwide. However, many recent viral outbreaks caused by different emerging and re-emerging viruses continue to be reported annually worldwide. It is therefore necessary to develop new control regimens.
