Efficient fabrication of structurally and functionally diverse nanomolecular devices and machines by organizing separately prepared DNA origami building blocks into a larger structure is limited by origami attachment yields. A general method that enables attachment of origami building blocks using ‘sticky ends' at very high yields is demonstrated. Two different rectangular origami monomers are purified...
Organizing DNA origami building blocks into higher order structures is essential for fabrication of large structurally and functionally diverse devices and molecular machines. Unfortunately, the yields of origami building block attachment reactions are typically not sufficient to allow programed assembly of DNA devices made from more than a few origami building blocks. To investigate possible reasons...
The stability of the nucleosome core particle (NCP) is believed to play a major role in regulation of gene expression. To understand the mechanisms that influence NCP stability, we studied stability and dissociation and association kinetics under different histone protein (NCP) and NaCl concentrations using single-pair Förster resonance energy transfer and alternating laser excitation techniques....
The first demonstration of a DNA‐based molecular machine constructed from two DNA origami tiles is presented on page 568. E. Nir and co‐workers connected two tiles to create a track on which a bipedal DNA walker travels back and forth with an operational yield similar to that of a motor striding on a single origami tile. This demonstrates the feasibility of dynamic DNA molecular machines that are...
In this work, the successful operation of a dynamic DNA device constructed from two DNA origami building blocks is reported. The device includes a bipedal walker that strides back and forth between the two origami tiles. Two different DNA origami tiles are first prepared separately; they are then joined together in a controlled manner by a set of DNA strands to form a stable track in high yield as...
Pulsed electrodeposition at room temperature is shown to be a facile, simple and fast method for super-filling of CuSCN onto ZnO nanowire arrays for applications in transparent diodes and optoelectronic devices. Compared to previously suggested methods for CuSCN superfilling, it offers the advantages of low cost, room temperature deposition in a one-pot process, combined with fast deposition rates,...
