Advancement of nanotechnology leads to the synthesis of nanomaterials with a well-defined dimensions and high mono-dispersity. An attractive possibility of green nanotechnology is to use microorganisms in the synthesis of nanoparticles. The present study reports the synthesis of zinc oxide nanoparticles using fungus Aspergillus fumigatus JCF. The production of zinc oxide nanoparticles was confirmed by the formation of white aggregates of zinc oxide nanoparticles. The optical properties of the nanoparticles were analyzed using UV–vis spectroscopy. The characteristic functional groups were analyzed using Fourier transform infrared spectroscopy. Particle size and morphology were analyzed using scanning electron microscope. Anti-microbial activity of zinc oxide nanoparticles towards both gram negative bacteria (Klebsiella pneumoniae, Pseudomonas aeruginosa and Escherichia coli) and gram positive bacteria (Staphylococcus aureus and Bacillus subtilis) were studied using well diffusion method.
