Kinesin biomolecular motors can be used to transport a range of metallic and semiconductor nanoparticles. On page 4476, George Bachand and co-workers report the self-assembly of nonequilibrium nanocomposites consisting of microtubule filaments and nanocrystal quantum dots. The cyclic assembly and disassembly of these composites are driven by the dynamic interaction of energy-dissipative (biomolecular transport) and thermodynamic processes (noncovalent bond formation).
