Investigation into the surface modification of Ti-6Al-4V to facilitate antimicrobial ionic silver integration for use in implantable orthopaedic devices
… the implant surface by free-swimming bacteria. Silver has a relatively low toxicity level of 28 mg/kg in the body. Current research has focussed mainly on reducing bio-inertness and improving the antimicrobial properties of titanium via the incorporation of silver. In general, the studies …

Assessing interactions between nutrients and aquatic toxicity : influences of nitrogen and phosphorus on ionic silver toxicity to the aquatic macrophyte Lemna gibba.
Though nutrients and silver often co-occur in aquatic ecosystems, the combined effects of these environmental stressors on aquatic plants are poorly understood. Such coexposures are important because nanosilver is increasingly released to the environment, and recent studies indicate that the …

The Performance of Silicon Based Sensor and its Application in Silver Toxicity Studies
… based sensor is able to detect part per trillion ionic silver in 0.0098% hydrofluoric acid based on the open circuit potential (OCP) measurement. The OCP jump of 100 ppt ionic silver solution is up to 120 mV. The complex agent can effectively suppress the ionic silver concentration and suppress …

Bacterial Responses to Silver Nanoparticle Treatment: Community Structure, Resistance, and Function.
<p>The antimicrobial properties of silver have been taken advantage of by societies for thousands of years. Its use has come back in favor in the form of silver nanoparticles, which are highly efficacious antimicrobial agents. Silver nanoparticles are incorporated into a myriad of products …

Predictive Modelling of the Growth of Nanoscale Silver Particles: Verification of an Aggregative Growth Mechanism
… study, we examine the formation of nanoscale silver particles from the reduction of silver salt using sodium borohydride. Within seconds of mixing silver salt solution with borohydride, >95% of the ionic silver is consumed, leaving essentially no silver for classical growth by molecular …

Inorganic Nanoparticle Nucleation on Polymer Matrices
… of the material. Metallic nanoparticles, like silver and gold, have been introduced into polymers for use as antimicrobial coatings or dielectric materials, respectively. The challenge in creating these materials currently is the difficulty to homogeneously disperse the particles throughout the …

Assessment of the use of ceramic water filters with silver nitrate as point-of-use water treatment devices in Dertig, North West Province, South Africa
… filters and finding an appropriate method for silver application so as to produce filters that are effective in both the provision of clean drinking water and the release of silver levels that are safe for human consumption. An assessment of the efficiency of ceramic water filters made with …
