In a similar way we could fabricate a nanoscale battery from a combination of two DNA origami plates covered by different materials for the appropriate combination of cathode and electrode, in this case with a conductive electrolyte between them. We envisioned that the design could be improved by the use of the additional third DNA origami layer, positioned between cathode and anode. The central DNA origami layer functions as an ion permeable membrane that prevents shortcircuiting of the conductive material deposited on each of the two side layers.</span><br><br>

<br> <br> <span style="font-family: Arial;"> The progressive improvement of microlitographic techniques underlined the advancement of miniaturization and high density integration of electronic components, supporting the well known Moore's law. However, many believe Moore's law is coming to a halt due to limitations of top-down approaches for device downsizing. Molecular self-assembly approach may be able to offer alternative solutions.<br> <br> Use of DNA as the template for the formation of conductive wires has already been demonstrated (and use of DNA origami as the template for carbon nanotube electronic switch has been reported (Maune, 2010).<br> <br> We propose to extend application of DNA origami based on the formation of vertical stacks for nanoscale electronic components.<br> <br> Surface of DNA origami can be covered with conductive layer, such as a network of intersecting carbon nanotubes or metalized surface.<br> <br> Vertical DNA origami stacks allow us to arrange two or more conductive surfaces and separate them by a defined distance.<br> <br> Separation of two conductive surfaces by a dielectric constitutes a capacitor. Therefore vertical stack of conductive DNA origami separated by a dielectric functions as a nanoscale capacitor.<br> </span> <table

In this illustration a percolating network of carbon nanotubes covers one surface of each plate, which can be achieved through incorporation of single-stranded extensions of staples into one surface of each DNA origami. Tethers between two conductive layers can be either DNA or using protein tethers (as shown here), the latter being probably more rigid and serve as isolator. The dielectric layer between the two conductive plates could be filled with a nonpolar polymer such as e.g. lipid bilayer, which could self-assemble to the surface of a DNA layer via headgroup interactions.</td>

</table> <span style="font-family: Arial;"> In a similar way we could fabricate a nanoscale battery from a combination of two DNA origami plates covered by different materials for the appropriate combination of cathode and electrode, in this case with a conductive electrolyte between them. We envisioned that the design could be improved by the use of the additional third DNA origami layer, positioned between cathode and anode. The central DNA origami layer functions as an ion permeable membrane that prevents shortcircuiting of the conductive material deposited on each of the two side layers.</span><br> <br> <table

</table> <span style="font-family: Arial;"> In addition to those two devices vertical stacks could be used as masks for the nanolitography for the deposition of a pattern of different materials onto different layers. Nanoscale dimensions and self-assembly process make those ideas potentially very appealing for technological applications, since there is an need for massively produced miniaturized tags and other electronic and optical nanodevices.</span><br> <br> <hr style="width: 100%; height: 2px;"><br> <ul>
