Nano, Silver, and You


NECN broadcast this SciTech Today segment on January 28, 2009, and it explains some of the potential risks and benefits of silver nanoparticles in consumer products. Nano-sized particles of silver are terrific at fighting bacteria and mold, and are being used in hospital settings and for food storage.

Some scientists believe silver nanoparticles in a rapidly increasing array of consumer products could impair the effectiveness of wastewater treatment plants, and accumulate in rivers and streams, harming wildlife.
