Antibacterial activity of nano-SiO2 Antibacterial Agent grafted on wool surface
Surface & Coatings Technology, 2007Co-Authors: Shuhua Wang, Wen Sheng Hou, Liqiao Wei, Husheng Jia, Xuguang LiuAbstract:Abstract A composite Antibacterial Agent of Ag-loaded nano-SiO 2 was prepared by adsorption methodology and grafted on wool surface. The Antibacterial performance of the Antibacterial wool fibers was tested for different concentration of composite Antibacterial Agent, contact time with germs and washing time. The content of the composite Antibacterial Agent grafted on wool fibers was easily controlled by varying the Antibacterial Agent concentration in the grafting process. The results showed that Antibacterial activity increased with the increasing concentration of the composite Antibacterial Agent. The Antibacterial wool fibers grafted 4.3% of composite Antibacterial Agent was highly effective in killing test bacteria and had excellent water-resisting property.

the structural analysis of biomacromolecule wool fiber with ag loading sio2 nano Antibacterial Agent by uv radiation
Journal of Photochemistry and Photobiology A-chemistry, 2007Co-Authors: Mei Niu, Wensheng Hou, Liqiao Wei, Xuguang LiuAbstract:Abstract The wool fiber with Ag-loading SiO 2 nano-Antibacterial Agent was prepared by the method of photografting. The structure of subsequent Antibacterial wool fiber was discussed in detail. The morphologies, structures and compositions were characterized by using Scanning Electronic Microscope (SEM), Transmission Electronic Microscope (TEM) and Fourier Transformation Infrared Spectrum (FTIR). The results showed that under ultraviolet irradiation the structure of wool fiber was changed, a lot of active groups were formed and grafting with Ag-loading SiO 2 was realized. Thus an Antibacterial layer was formed on the surface of wool fiber by covalent bonding and a lasting Antibacterial performance was obtained.

Silver as Antibacterial Agent: Ion, nanoparticle, and metal
Angewandte Chemie - International Edition, 2013Co-Authors: Svitlana Chernousova, Matthias EppleAbstract:The Antibacterial action of silver is utilized in numerous consumer products and medical devices. Metallic silver, silver salts, and also silver nanoparticles are used for this purpose. The state of research on the effect of silver on bacteria, cells, and higher organisms is summarized. It can be concluded that the therapeutic window for silver is narrower than often assumed. However, the risks for humans and the environment are probably limited.

in vitro activity of tr 700 the active ingredient of the Antibacterial prodrug tr 701 a novel oxazolidinone Antibacterial Agent
Antimicrobial Agents and Chemotherapy, 2009Co-Authors: Ronda D Schaadt, Debora Sweeney, Dean L Shinabarger, Gary E ZurenkoAbstract:TR-701 is the prodrug of the microbiologically active molecule TR-700, a novel orally and intravenously administered oxazolidinone Antibacterial Agent. The in vitro activity of TR-700 was evaluated against 1,063 bacterial clinical isolates including staphylococci, enterococci, streptococci, Moraxella catarrhalis, Haemophilus influenzae, and a variety of anaerobic bacterial species. The test strains were recent (2005 to 2008) clinical isolates from diverse U.S. (80%) and non-U.S. (20%) sites. MIC assays were conducted using reference broth microdilution and agar dilution methods with the principal comparators linezolid and vancomycin. TR-700 was four- to eightfold more potent than linezolid against staphylococci and generally fourfold more potent against enterococci and streptococci. TR-700 was less active against M. catarrhalis and H. influenzae but was twofold more active than linezolid. Against anaerobic species, the activity of TR-700 was equivalent to or up to fourfold higher than that of linezolid. These results indicate that TR-700 is a promising new oxazolidinone Antibacterial Agent with greater in vitro potency than linezolid against clinically important gram-positive bacteria.
