Abstract

Nanosilver Fluoride (NSF) is an emerging anticaries material with demonstrated antimicrobial properties that do not cause staining on carious lesions. However, its availability for research and development remains limited, particularly regarding variations in its synthesis methods, which can affect its physicochemical properties. This study focused on the physicochemical characteristics of NSF synthesized through two distinct methods: chemical synthesis and the use of commercially available colloidal nanosilver. Both versions of NSF were characterized using Ultraviolet-Visible (UV-Vis) spectrophotometry and Transmission Electron Microscopy (TEM). The chemically synthesized NSF exhibited an absorption band at 400-410 nm, while the colloidal nanosilver-based NSF demonstrated no peak from the UV-Vis absorption. TEM analysis revealed that the Silver Nanoparticles (AgNPs) in the chemically synthesized NSF had a mean diameter of 4.99±0.83 nm, compared to the 3.50±0.74 nm diameter observed in the colloidal silver-based NSF. These findings highlight that different synthesis methods yield significant differences in nanoparticle size and absorption characteristics. In conclusion, while both methods are viable for NSF production, researchers should carefully consider the synthesis approach, especially when using commercially available colloidal silver, as it may result in varying properties that could impact the material’s efficacy.
