Nano-velcro binds faster than strongest glues: Super-strong adhesive planned with hooked carbon strands.: "Nano-velcro could hold objects together as tightly as a strong adhesive, say US researchers1.
The reusable material is carpeted with hook-ended carbon tubes, each just millionths of a millimetre across. It could fasten components in ultra-small robots, propose David Tománek and colleagues at Michigan State University in East Lansing."
nice pics even.
