DNA 3D Nand Gate Bricks Would Be Able to Make a Computer with 1 million times the transistors of Intel Itanium Poulson Computers
From
Harvard researchers have used single strand DNA, to self assemble custom designed nano scale structures. Each of the bricks shown to the left is, 25-nanometers on a side, they are composed of ~1,000 voxels (I think it is 500 DNA strand, 2 voxels per strand) unique single strands of DNA, each with 32 nucleotides. Each strand is like a jigsaw puzzle piece and can only bind in one location. This is due to the fact that nucleotides only bind to their opposites, A to T and G to C. These DNA strands can be designed to self assemble into pretty much any shape, as shown in the image.
David Fuchs at Hephastus Project outlines what kind of computing would be possible with 25 nanometer 3D Nand bricks.
A one inch cube could hold 1,000,000,000,000,000,000 of these 25 nm bricks.
Using two simple techniques, you can build much larger structures out of smaller ones. The first technique is to create binding sites, on each of the six sides of the brick. The second technique is to create a spacer-binder with matching but opposite nucleotides to bind to.
