| 摘要 |
The present invention refers to an antibacterial composition against Gram positive and Gram negative bacteria, which contains silver nanoparticles (Ag NPs) with average diameter of approximately less than 15 nm that have a photocatalytically inactive surface, present in a range between 8.5 and to 70% in weight regarding the total composition, in which Ag NPs are the antibacterial agent that remains homogeneously exposed by a ceramic dispersing agent like TiO2 and its bactericidal activity is generated in presence of UV-visible light and/or in the dark. |
