Tiny spikes on a silicon surface can stab and kill any bacteria that make contact, researchers report November 26 in Nature Communications. Scientists could foil infectious bacteria by using the new surface architecture as a coating on medical devices and food-processing equipment.

Microbiologist Elena Ivanova of Swinburne University of Technology in Hawthorn, Australia, and colleagues designed the nanoarchitecture by taking cues from bacteria-free surfaces in nature such as insect wings. Usin...
