Cysteine-silver complexes were prepared and investigated the antimicrobial activity on rubber mat manufactured with waste rubber. We are exposed to harmful bacteria and fungi all the time. We manufactured antimicrobial mat to be imposed to mats that it can prevent generation of bacteria and microorganisms, and restrict their reproduction. Infection of medical devices causes significant morbidity and mortality. For aim of this study, we measured the antimicrobial mat manufactured with cysteine-Ag complex by CCD, FT-IR and NMR. The effect of mole ratio of cysteine-Ag complex on antimicrobial activity to bacteria and fungi is investigated. Reduction rate is evaluated using the Quinn method. Antimicrobial activity of complex on mole ratio 1:4 was effectively inhibited. The complexes had a better antibacterial activity than antifungal activity on rubber mat.
