Nanofabrication by self-assembly

Computing by molecular self-assembly.

The paper reviews two computing models by DNA self-assembly whose proof of principal have recently been experimentally confirmed. The first model incorporates DNA nano-devices and triple crossover DNA molecules to algorithmically arrange non-DNA species. This is achieved by simulating a finite-state automaton with output where golden nanoparticles are assembled to read-out the result. In the se...

Nano Wires by Self Assembly

We present a technique to fabricate nano wires on silicon substrates without any lithography. The wires are 50 nm or less in width, but their lengths can be 10s of micro meters. They can be formed by a single or multiple layers of metals. The wires can be designed to form a network which can be partially released from the substrate to form 3D structures. Such structures may serve as actuators o...

DNA Computing by Self-Assembly

Information and algorithms appear to be central to biological organization and processes, from the storage and reproduction of genetic information to the control of developmental processes to the sophisticated computations performed by the nervous system. Much as human technology uses electronic microprocessors to control electro-mechanical devices, biological organisms use biochemical circuits...

Nanopropulsion by biocatalytic self-assembly.

A number of organisms and organelles are capable of self-propulsion at the micro- and nanoscales. Production of simple man-made mimics of biological transportation systems may prove relevant to achieving movement in artificial cells and nano/micronscale robotics that may be of biological and nanotechnological importance. We demonstrate the propulsion of particles based on catalytically controll...
