Preparation and antibacterial activity of silver nanoparticles impregnated in bacterial cellulose

Preparation and Antibacterial Activity of Silver Nanoparticles

Uniform silver nanoparticles have been prepared through the chemical reduction of silver ions by ethanol in presence of sodium linoleate. TEM micrograph shows a uniform distribution of the particles with an average size of 12 nm. Further, the antimicrobial activity of silver nanoparticles shows that these nanoparticles can be used as effective growth inhibitors against Staphylococcus Basillus, ...

Carboxymethylchitosan nanofibers containing silver nanoparticles: Preparation, Characterization and Antibacterial activity

Article history: Received on: 28/01/2016 Revised on: 17/03/2016 Accepted on: 18/05/2016 Available online: 28/07/2016 Herein we prepare antibacterial composite from carboxymethylchitosan (CMCS) nanofibers and silver nanoparticles (AgNPs) by using poly (vinyl alcohol) (PVA) as reducing, capping and fiber aiding material and investigated to be used in biomedical applications. The AgNPs has spheric...

Chlorhexidine-silver sulfadiazine-impregnated central venous catheters: in vitro antibacterial activity and impact on bacterial adhesion.

The aim of this study was to compare the in vitro activity and the impact on bacterial adhesion of two different catheters, one impregnated with chlorhexidine-silver sulfadiazine (C-SS) and the other not impregnated with antibacterial agents. The antimicrobial coating prevented the bacterial colonization by slime positive Staphylococcus epidermidis in the first two days. The antibacterial activ...

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...
