Effect of Surfactants and Polymers on Stability and Antibacterial Activity of Silver Nanoparticles (NPs)
In this first systematic study, we describe the influence of various surfactants and polymers on aggregation stability and antibacterial activity of silver nanoparticles (NPs) prepared by a modified… Expand

Initial Study on the Toxicity of Silver Nanoparticles (NPs) against Paramecium caudatum
In this initial study, the toxicity effect of silver NPs against a model unicellular eukaryotic organism of Paramecium caudatum was studied. For the purpose of this study, a dialysis-based method was… Expand
The influence of complexing agent concentration on particle size in the process of SERS active silver colloid synthesis
A one-step chemical reduction route towards silver colloid particles with controllable sizes ranging from 45 to 380 nm is reported in this article. Silver particles, prepared by the reduction of… Expand
The targeted antibacterial and antifungal properties of magnetic nanocomposite of iron oxide and silver nanoparticles.
Two kinds of silver nanocomposites are well applicable for a targeted magnetic delivery of silver nanoparticles in medicinal and disinfection applications and the non-cytotoxic nature of the polyacrylate linker. Expand
Bacterial resistance to silver nanoparticles and how to overcome it
It is reported that the Gram-negative bacteria Escherichia coli 013, Pseudomonas aeruginosa CCM 3955 and E. coli CCM 3954 can develop resistance to silver nanoparticles after repeated exposure, and the resistance mechanism cannot be overcome by additional stabilization ofsilver nanoparticles using surfactants or polymers. Expand
Strong and Nonspecific Synergistic Antibacterial Efficiency of Antibiotics Combined with Silver Nanoparticles at Very Low Concentrations Showing No Cytotoxic Effect
A very low amount of silver is needed for effective antibacterial action of the antibiotics, which represents an important finding for potential medical applications due to the negligible cytotoxic effect of AgNPs towards human cells at these concentration levels. Expand
