The University of Vermont has developed a wrench that has linewidth geometries at 1.7nm. The so-called nano-wrench is an atomic-level tool, which could one day be used to create tiny structures and molecules.
The nano-wrench has been devised using a technology called chirality-assisted synthesis (CAS). Chirality is derived from the Greek word for hand. If one holds u... » read more
