Silver cations are highly toxic to bacteria as they damage the DNA and RNA, damage and inhibit membrane proteins and enzymes and induce the formation of reactive oxygen species [1]. The aim of this project is to combine the antimicrobial silver with other antimicrobial active metals like copper or zinc [2, 3, 4] in bimetallic and bioinspired complexes to create a synergistic effect against bacteria. Moreover, this project will investigate the use of such complexes in biomedical scaffolds and coatings for applications in tissue engineering and medical implants.
