摘要

The antibacterial effect of Fe-based,Ni-based and Cu-based metallic glasses has been studied in this research.All test metallic glasses were found to inhibit growth of Esherichia coli.The optical density value of E.coli flocculation exposed to metallic glasses,from which the number of bacteria was determined,was 65% lower than that of the match group,and 57% lower than that of the ferrite group.Moreover,the antibacterial effect was not significantly different(σ=0.05) between Cu-based,Ni-based and Fe-based metallic glasses.These results extend our understanding of the antibacterial effect of metallic antibacterial materials,and suggest new applications for metallic glasses.
