This article reports that plastic storage containers and food packaging could soon be manufactured with built-in anti-microbial properties, following the creation of low-cost, polymercompatible gold and silver nonpareils. The development by US company NanoHorizons of Pennsylvania represents the first commercially available noble metal nanoparticles engineered for use in plastic or nylon-based products. The company claims its nanoparticles are 90 per cent cheaper than its competitors, and can also be provided in organic solvents, making them easily integrated within current manufacturing processes.
