in and colleagues report that their nanonails have all-purpose repellency properties. The nails actually are submicroscopic silicon structures shaped like carpenters nails that dramatically enhance a surfaces repellency. However, the surface becomes highly wettable when electricity is applied, allowing liquid to be sucked between the nails. In laboratory demonstrations, the researchers showed that their electronic non-stick surface works effectively using virtually any liquid.

Nanonails also show promise for enhancing chemical microreactions, decreasing flow resistance, and facilitating liquid movement for medical diagnostic applications such as lab-on-a-chip technology, they say. MTS
