SLIPS blitz biofilms

摘要

Coating solids with immobilized liquids could help to deal with dangerous bacterial biofilms. Many bacterial species form durable slimes that can cover everything from medical devices to ship hulls. Joanna Aizenberg at Harvard University in Cambridge, Massachusetts, and her team showed that slippery liquid-infused porous surfaces (SLIPS) - in which a liquid is 'locked' onto a solid through affinities between the two - can resist biofilm growth.
