Method Could Resolve Nanosilver's Cloudy Toxicity Picture - Nanomaterials: Cloud point extraction could help distinguish between silver nanoparticles and silver ions

Abstract:
For toxicologists, silver nanoparticles present a conundrum: Does their toxicity in the environment stem from the nanoparticles themselves or from the silver ions that slough off the particles? Measuring these different forms of silver can be difficult. Now researchers have developed a method that can distinguish the two in simple lab samples (Anal. Chem., DOI: 10.1021/ac201086a).

Manufacturers add silver nanoparticles to consumer products such as clothing to exploit the particles' antimicrobial properties. But the particles can wash off of products into wastewater. Scientists worry about their presence in the environment because studies have demonstrated that nanosilver can harm organisms such as algae (Environ. Sci. Technol., DOI: 10.1021/es801785m)
