DNA origami has rapidly emerged as a powerful technique to fabricate user‐defined DNA nanostructures. However, the ability to custom‐make patterns on DNA origami template is hampered by the heavy workload and high cost of changing staple DNA (up to several hundred strands per set). Here, a scaffold‐decorated DNA origami method is developed by prescribing the pattern information to the scaffold DNA...
The atomic structure of free‐standing graphene comprises flat hexagonal rings with a 2.5 Å period, which is conventionally considered the only atomic period and determines the unique properties of graphene. Here, an unexpected highly ordered orthorhombic structure of graphene is directly observed with a lattice constant of ≈5 Å, spontaneously formed on various substrates. First‐principles computations...
In article number 1902637, Guosheng Shi, Yi Zhang, and co‐workers discover an orthorhombic crystal of graphene with an ≈5 Å period formed on various substrates, which can be applied to control the epitaxial self‐assembly of amyloid peptides. First‐principle computations show that this atomic structure can be attributed to dipoles between the graphene surface and substrates.
DNA nanotechnology enables the precise fabrication of DNA‐based machines with nanoscale dimensions. A wide range of DNA nanomachines are designed, which can be activated by specific inputs to perform various movement and functions. The excellent rigidity and unprecedented addressability of DNA origami have made it an excellent platform for manipulating and investigating the motion behaviors of DNA...
