Abstract

In this work, an ecofriendly and economic strategy for synthesize of CuO and Co O were developed using extracted Sesba- 3 4 nia sesban solution (ESS) as a reducing and stabilizing agent, and bioreactor. These novel nano metal oxides (NMOs) were characterized by high-resolution-transmission electron microscopy (TEM), EDAX thermo gravimetric analysis and X-ray diffraction (XRD). Morphology and size of them were investigated by TEM and the average sizes of for spherical CuO and Co O nanoparticles are 20–40 and 15–30 nm, respectively. The XRD and EDAX confirmed the high purity for NMOs. The 3 4 thermal behaviors of the NMOs exhibited good crystallographic stability within the investigated temperature range. The anti- oxidant and antibacterial activities of NMOs were investigated and compared to manganese(III) meso-tetraphenylporphyrin complex/Ag nanocomposite (Ag/P nanocomposite) synthesizing by ESS. The results obtained from this work showed that copper(II) oxide, cobalt oxide nanoparticles, and Ag/P nanocomposite have DPPH scavenging activity. On the other hand, NMOs have no antibacterial activity against Gram-negative bacterial strains. Cobalt oxide nanoparticles have antibacterial activity against Staphylococcus aureus, while Ag/P nanocomposite showed the antibacterial activities against both Gram- negative and Gram-positive bacterial strains.
