Antifungal activity of silver nanoparticles against Candida spp.
The antifungal activity of the silver nanoparticles (NPs) prepared by the modified Tollens process was evaluated for pathogenic Candida spp. by means of the determination of the minimum inhibitoryExpand
Silver colloid nanoparticles: synthesis, characterization, and their antibacterial activity.
The reduction of [Ag(NH(3))(2)](+) by maltose produced silver particles with a narrow size distribution with an average size of 25 nm, which showed high antimicrobial and bactericidal activity against Gram-positive and Gram-negative bacteria, including highly multiresistant strains such as methicillin-resistant Staphylococcus aureus.

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 modifiedExpand
Acute and chronic toxicity effects of silver nanoparticles (NPs) on Drosophila melanogaster.
The long-term exposure to silver NPs influenced the fertility of Drosophila during the first three filial generations, nevertheless the fecundity of flies in subsequent generations consequently increased up to the level of the flies from the control sample due to the adaptability of flies to thesilver NPs exposure.

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 wasExpand
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 ofExpand
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.

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
Enhanced antibacterial effect of antibiotics in combination with silver nanoparticles against animal pathogens.
The study shows that AgNPs have potential as adjuvants for the treatment of animal bacterial diseases and the highest enhancement of antibacterial activity was found with combined therapy together with penicillin G against Actinobacillus pleuropneumoniae. Expand
