Hyaluronan and Heparin Reduced Silver Nanoparticles Having Antimicrobial Properties, M. M. Kemp, A. Kumar, D. Clement, P. Ajayan, S. Mousa, R. J. Linhardt, Nanomedicine, 4, 421-429, 2009.
Abstract
Aims: Silver nanoparticles exhibit unique antibacterial properties that make these ideal candidates for biological and medical applications. We utilized a clean method involving a single synthetic step to prepare silver nanoparticles that exhibit antimicrobial activity. Materials & methods: These nanoparticles were prepared by reducing silver nitrate with diaminopyridinylated heparin (DAPHP) and hyaluronan (HA) polysaccharides and tested for their efficacy in inhibiting microbial growth. Results & discussion: The resulting silver nanoparticles exhibit potent antimicrobial activity against Staphylococcus aureus and modest activity against Escherichia coli. Silver–HA showed greater antimicrobial activity than silver–DAPHP, while silver–glucose nanoparticles exhibited very weak antimicrobial activity. Neither HA nor DAPHP showed activity against S. aureus or E. coli. Conclusion: These results suggest that DAPHP and HA silver nanoparticles have potential in antimicrobial therapeutic applications.
