<i>ACS Applied Nano Materials</i> Cover (IMAGE) University of Pittsburgh Caption The ACS Applied Nano Materials cover illustrates a new approach for creating helix-rich RSF films based on molecular interactions between the protein molecules and carboxyl-functionalized surfaces of a small quantity of added carbon nanotubes (CNTs). Local heating of CNTs using microwave irradiation (depicted here as glowing red) then leads to the formation of helical conformations in fibroins near the CNTs.
