title: Thymine and adenine tetrads formed on anisotropic metal surfaces.
abstract: The interplay of the Au(110) surface and alkyl-substituted DNA bases induces reorganization of the surface with parallel atomic grooves, while the enhanced surface anisotropy constrains the substituent alkyl chains along the grooves. Every four molecules are bound together through H-bonds while further possible H-bonds are prohibited by either the alkyl chains or the groove borders, resulting in separated tetrad structures located in the grooves.
