Antimicrobial silver nanoparticles appear in a wide variety of products, including medical equipment and even socks. But silver nanoparticles can linger in the environment and may pose a threat to natural ecosystems. Now, an international research team has developed potentially eco-friendly, silver-infused nanoparticles that effectively combat bacteria (Nat. Nanotechnol. 2015, DOI: 10.1038/nnano.2015.141).

The new antimicrobial is built around lignin, a by-product of wood pulp processing. The team’s lignin nanoparticle cores carry only 5 to . . .
