Synthesis of CdO NPS for antimicrobial activity

: In this study, (50 - 110) nm cadmium oxide (CdO) nanoparticles were synthesized by chemical method. The optical, structural and topographical properties of the synthesized nanoparticles were investigated by using UV-VIS absorption, Transmission electron microscopy TEM, atomic force microscopy AFM, and x-ray diffraction XRD. The bacterial resistance represents a problem and the outlook for the use of antibiotics in the future is still uncertain. Therefore, it must be taken measures to reduce this problem. Antibacterial activity of the Cadmium oxide nanoparticles were investigated against several pathogenic bacteria, including Klebsiella pneumoniae; Acinetobacter baumannii; Pseudomonas aeruginosa and Staphylococcus aureus by using well diffusion method ,the results showed that Cadmium nanoparticles had inhibitory effect against all pathogenic bacteria with inhibition zone (18 ,18 ,14 and 17 mm) for S. aureus, K. pneumonia, A. baumannii and P.aeruginosa respectively. CdO nanoparticles had inhibitory effect against S. aureus (22 mm) ; K. pneumonia ( 18mm) and A. baumannii (14mm)
