Abstract

Zinc oxide nanoparticles were synthesised from zinc nitrate using the aqueous extract of Brassica Oleracea vegetable. Green synthesis yielded zinc oxide nanoparticles which exhibited a blue shifted absorption peak at 224 nm in the UV-Visible spectrum. The surface morphology of zinc oxide nanoparticles were characterised using Scanning Electron Microscopy (SEM). The X-ray diffraction (XRD) pattern revealed a hexagonal wurzite structure; with the average particle size of 29 nm calculated using Debye – Scherrer’s formula. The anti-fungal activity of zinc oxide nanoparticles was evaluated against candida albicans. The zone of inhibition values obtained by disc diffusion method suggested that the synthesised ZnO nanoparticles are effective against candida albicans.

Keywords: Green synthesis, zinc oxide nanoparticles, Brassica Oleracea, antifungal activity, candida albicans.
