Micro-fastening system: nanovelcro

We have explored the suitability of nanotube-based hooks for bonding. Our results indicate that a large force of 3.0 nN is required to disengage two hooks, which are formed by the insertion of pentagon-heptaon pairs in a (7,0) CNT. Nanohooks based on various nanotubes are resilient and keep their structrual integrity during the opeing process. Arrays of hooks, which are permanetly anchored in solid surfaces, are a nanoscale counterpart of velcro fasteners, forming tough bonds with a capability of self-repair.

This micro-fastening system was rigisterd as a US patent (US7,181,811).
