Synthesis of Copper Nanoparticles by Thermal Decomposition and Their Antimicrobial Properties

الملخص EN

Copper nanoparticles were synthesized by thermal decomposition using copper chloride, sodium oleate, and phenyl ether as solvent agents.

The formation of nanoparticles was evidenced by the X-ray diffraction and transmission electron microscopy.

The peaks in the XRD pattern correspond to the standard values of the face centered cubic (fcc) structure of metallic copper and no peaks of other impurity crystalline phases were detected.

TEM analysis showed spherical nanoparticles with sizes in the range of 4 to 18 nm.

The antibacterial properties of copper nanoparticles were evaluated in vitro against strains of Staphylococcus aureus and Pseudomonas aeruginosa.

The antibacterial activity of copper nanoparticles synthesized by thermal decomposition showed significant inhibitory effect against these highly multidrug-resistant bacterial strains.
