Antifungal Activity of Iron-gold and Cobalt-gold co-doped ZnO Nanoparticles

Zn_0.98Fe_0.01Au_0.01O and Zn_0.98Co_0.01Au_0.01O nanoparticles (NPs) have been synthesized via poly ethylene glycol assisted route. The average crystallite size of Zn_0.98Fe_0.01Au_0.01O and Zn_0.98Co_0.01Au_0.01O 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 Zn_0.98Fe_0.01Au_0.01O and Zn_0.98Co_0.01Au_0.01O NPs were investigated. The antifungal activity of synthesized Zn_0.98Fe_0.01Au_0.01O and Zn_0.98Co_0.01
