Striped nanorods feel the strain

Abstract:
Stripy nanorods containing evenly spaced quantum dots have been prepared thanks to strain forces, report US nanochemists.

This is the first time that strain has been used to construct a '1D superlattice' of this sort without the need to fix the particles to a solid surface, said lead author Paul Alivisatos at the University of California at Berkeley. The free-standing colloidal particles 'can go where particles on a substrate can't go,' explained Alivisatos, opening up a host of biological and other applications.
