Antimicrobial properties of multimetallic of silver compounds immobilized on active carbon and nano carbon tubes

In this paper, some bi- and tri-metallic silver compounds (Ag50Ni50/CNT, Ag90Ni10/CNT, Ag70Ni30/CNT, Pd10Co10Ag80/AC, Pd20Co30Ag50/AC, Pd30Co30Ag40/AC, (AC; active carbon) (CNT; carbon nanotube)) were synthesized with the polyol method. Antibacterial activities against Staphylococcus aureus ATCC 29213, Enterococcus faecalis ATCC 29212, Escherichia coli ATCC 25952, Pseudomonas aeruginosa ATCC 27853 and Bacillus cereus ATCC 29213, and antifungal activity against Candida albicans ATCC 90028 were investigated. The standard protocols were evaluated in the experimental process. The antibacterial activity assay results were correlated with the morphological characterization of the material (scanning electron microscope energy dispersive X-ray spectroscopy). It was determined that all nanomaterials (NMs) had effective antifungal activity against C. Albican fungi, but Ag70Ni30/CNT had better antifungal effects than the other NMs. Only Ag70Ni30/CNT had antibacterial activity against B. cereus and P. aeruginosa bacteria pathogens. Therefore, the relevant NMs were introduced to the literature with this feature of antifungal and antibacterial activities. •All nanomaterials (NMs) had effective antifungal activity against C.
