| Abstract Scope |
Silver nanoparticles are highly toxic to several pathogenic fungal and bacterial species; for example, these nanoparticles demonstrate biocidal effects against Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, and other species of bacteria. The precise mechanism of action of silver nanoparticles has not been fully resolved; however, it is thought that silver ions interfere with electron transport system as well as prevent DNA replication. In addition, no bacterial resistance has been observed with the use of silver as an antimicrobial agent. In this presentation, the use of laser processes to create nanocomposite films containing silver nanoparticles will be considered. The structural characterization and antimicrobial performance of these films will be reviewed. These silver nanoparticle-containing nanocomposite films may provide antimicrobial properties to medical or household products. |
