In this paper, a biosensor has been fabricated using ZnO nanorods and nanoparticles to detect different concentrations of the E. coli bacteria. The innovation of this paper lies in design and fabrication of the resistive type E Coli bacteria sensor. To make this biosensors, printed circuit board based electrodes are designed and made in an interdigitated shape. Both hydrothermal and drop cast m...

In this study, the effect of simultaneous doping of magnesium, calcium, and copper ions on the properties of zinc oxide doped with cobalt was investigated. The sol-gel method has been used for the synthesis of nanoparticles. The structural and optical properties of the synthesized nanoparticles were investigated using X-ray diffraction (XRD), infrared spectroscopy (FTIR), and DRS spectroscopy. ...

Background: Studies have shown that metal nanoparticles are highly active and exhibits remarkable bactericidal activity against a wide range of bacteria. Objective: The aim of this study was to examine the antibacterial activity of zinc oxide nanoparticles against standard strains of Pseudomonas aeruginosa and Staphylococcus aureus and their isolates in food products. Methods: This experiment...

The efficacy of a molybdate formulation and a zinc oxide bolus as prophylactic agents for enzootic icterus was evaluated in sheep. Before copper loading, liver biopsies were performed on 12 male, 6-month-old, Mutton Merino sheep to determine hepatic copper (Cu) and zinc (Zn) concentrations. The animals were restrictively randomised according to liver copper concentrations to 3 treatment groups ...
