Silver nanoparticles capped with alginate (SNP-AL) were prepared by chemical reduction method. Three concentrations of SNP-AL were produced by varied alginate into 0.1, 1, and 5 mM. UV-Vis spectroscopy was used to characterize their specific wavelength at 400 nm. Subsequently, 10 bilayers thin film were established between PDADMAC and SNP-AL via polyelectrolyte multilayer technique. These were characterized by SEM and AFM. Their toxicity to anaerobe bacteria Aggregatibacter actinomycetemcomitans (Aa) a common cause of periodontal disease, was tested. Findings showed that these silver nano-chips could release SNP and reduce the Aa colony by 90%.
