Abstract
Zn0.98Fe0.01Au0.01O and Zn0.98Co0.01Au0.01O nanoparticles (NPs) have been synthesized via poly ethylene glycol assisted route. The average crystallite size of Zn0.98Fe0.01Au0.01O and Zn0.98Co0.01Au0.01O NPs were estimated from X-ray diffraction results and the values are 31.38 nm and 36.14 nm respectively. ...

Zn0.98Fe0.01Au0.01O and Zn0.98Co0.01Au0.01O nanoparticles (NPs) have been synthesized via poly ethylene glycol assisted route. The average crystallite size of Zn0.98Fe0.01Au0.01O and Zn0.98Co0.01Au0.01O NPs were estimated from X-ray diffraction results and the values are 31.38 nm and 36.14 nm respectively. The UV absorption spectra confirmed the formation of the NPs with the characteristic peaks at 374 and 366 nm respectively. This spectral observation indicates that the band gap of ZnO nanoparticles decreases by doping iron/gold and cobalt/gold nanoparticles. The morphology and elemental composition of Zn0.98Fe0.01Au0.01O and Zn0.98Co0.01Au0.01O NPs were investigated. The antifungal activity of synthesized Zn0.98Fe0.01Au0.01O and Zn0.98Co0.01Au0.01O NPs were found against four postharvest pathogenic fungi like Aspergillus niger, Aspergillus flavus, Rhizopus microsporus and Pencillium sp. The doping of iron and gold in ZnO nanoparticles enhances the zone of inhibition for the fungal pathogens compared to pure ZnO nanoparticles. Antifungal activity of Zn0.98Fe0.01Au0.01O and Zn0.98Co0.01Au0.01O nanoparticles were higher when compared with standard antibiotic mycostatin whose zone of inhibition is 18 mm against Aspergillus niger, Aspergillus flavus, Rhizopus microsporus and Pencillium sp.

The oral thrush caused by the cosmopolitan yeast Candida albicans causes pale white cottony patches in the oral regions especially among the Immuno deficient patients. The elderly patients with the diabetes were the main victims of the yeast thrush. The objective of our investigation is to collect the clinical thrush samples from the targeted elderly patients with type 2 diabetes between the age group of 58 to 75 and determine the antifungal activities of Salvia jordanii by employing the standard microbiological technique. The results procured were excellent for the antifungal susceptibility analysis of all five types of S. jordanii essential oil extracts. The MIC and MFC values of the extracts from the Jordanian, Syrian and Moroccan origin shown the same values, whereas the Libyan and Egyptian extract shown the slightly higher values. The nature blessed essential oil extracts got the potential to combat infections as well as to treat the oral thrush. These findings indicate that S. jordanii displays adequate activity against cosmopolitan yeast C. albicans in vitro & its merits. Further analysis to treat yeast associated diseases.
