Synthesis titanium dioxide nanoparticles doped with silver and Novel antibacterial activity

Silver-Doped Nanoclay with Antibacterial Activity

The aim of this study was to synthesize Ag-nanoclay composite by solid ion exchange, then characterize, and evaluate the antibacterial activity. This newly introduced ion exchange is a simple and low cost technique, which provides a quicker method. Without chemical treatment, nanoclay was subjected to an ion exchange process in media containing molten salt of silver at 300 and 400 °C and at dif...

Synthesis, Characterization and Antibacterial Properties of Titanium Dioxide Nanoparticles

Biocompatibility and antibacterial activity of nitrogen-doped titanium dioxide nanoparticles for use in dental resin formulations

The addition of antibacterial functionality to dental resins presents an opportunity to extend their useful lifetime by reducing secondary caries caused by bacterial recolonization. In this study, the potential efficacy of nitrogen-doped titanium dioxide nanoparticles for this purpose was determined. Nitrogen doping was carried out to extend the ultraviolet absorbance into longer wavelength blu...

Synthesis and characterization of silver nanoparticles for antibacterial activity

We consider of the antimicrobial activity on the Ag nanoparticles(Ag NPs) aqueous solutions, which was prepared using a stabilizer, such as poly(N vinyl 2 pyrrolidone PVP , for Staphylococcus aureus) S aureus and Escherichia coli E coli by measuring the minimum inhibitory concentration MIC . Antimicrobial effect of Ag NPs for S aureus and E coli was investigated using disk diffusion method Also...

Synthesis of silver nanoparticles and their antibacterial activity

In study, spherical Silver nanoparticles (SNPs) were synthesized by chemical reduction method from a metal precursor silver nitrate in presence of an anionic surfactant and strong reducing agent. In this experimental work, SNPs are synthesized in presence of different concentration of stabilizing agent and effect of stabilizing agent on size distribution of SNPs have been observed. Further anti...
