An antibacterial mechanism of titanium alloy based on micro-area potential difference induced reactive oxygen species
Shan Fu,Yuan-Ting Zhang,Yi Wei Yang,Xiaomeng Liu,Xinxin Zhang,Lei Yang,Dake Xu,Fuhui Wang,Gaowu Qin,Er-Wei Zhang +9 more
TL;DR: In this article , the micro-area potential difference (MAPD) on the surface of titanium alloys has been found to be a key factor in the antibacterial properties of the alloys, and it was shown that high MAPD is associated with great production of reactive oxygen species (ROS), resulting in the killing effect to the biofilm known to be associated with implant infections.

The bactericidal effect of silver nanoparticles
Jose Ruben Morones,Jose Luis Elechiguerra,A. Camacho,Katherine B. Holt,Juan B. Kouri,Jose Tapia Ramirez,Miguel Jose Yacaman +6 more
TL;DR: The results indicate that the bactericidal properties of the nanoparticles are size dependent, since the only nanoparticles that present a direct interaction with the bacteria preferentially have a diameter of approximately 1-10 nm.

A mechanistic study of the antibacterial effect of silver ions on Escherichia coli and Staphylococcus aureus.
TL;DR: The existence of elements of silver and sulfur in the electron-dense granules and cytoplasm detected by X-ray microanalysis suggested the antibacterial mechanism of silver: DNA lost its replication ability and the protein became inactivated after Ag(+) treatment.
