The prepared cobalt oxide nanoparticles were manufactured in the first and second methods, and they show the properties of the nanomaterials for all solutions of plant extracts. XRD examination showed (440) 65, (622) 79, while Sem's examination showed the appearance with a size of 10-25 nm. Tem examination gave that nanoparticles with a size not exceeding 0.5-60 nm. The UV absorbance and permeability test indicated that the nanomaterial is at a value between 236-800nm, and energy gap values of 2.0-3.8 ev. Ft-ir assay shows that the bonding sites for cobalt oxide are at (±50) (505 to 694), and the Zeta Potential test indicated that all the particles of the solutions have very small values and that the material is not agglomerating. The Aleo vera plant extract with cobalt oxide nanomaterial, where the diameters of the inhibition zones were (35, 35, 45) mm, respectively, for the growth of both Ps.aeruginosa, S. aureus and E.coli bacteria. The results of the effect of cobalt oxide solutions on the inhibition of the growth of fungi were great, and that the nanomaterial was also sweeping, showing the absence of fungal growth Trichophyton mentagrophytes.
