Nanotech Roundup:Platform for Supramolecular Nanoassembly, 3d 100nanometer cubes, nanoelectromechanical single-atom switch
1. Platform for Controlled Supramolecular Nanoassembly We here present a two-dimensional (2D) micro/nano-fluidic technique where reactant-doped liquid−crystal films spread and mix on micro- and nanopatterned substrates. Surface-supported phospholipid monolayers are individually doped with complementary DNA molecules which hybridize when these lipid films mix. Using lipid films to convey reactants reduces the dimensionality of traditional 3D …
