DNA wires made and formed into patterns

Ohio State University researchers have invented a process for uncoiling long strands of DNA and forming them into precise patterns. Ultimately, these DNA strands could act as wires in biologically based electronics and medical devices They used a tiny rubber comb to pull DNA strands from drops of water and stamp them onto glass chips. …

Other technology: plastic circuits, pre-nano desktop manufacturing

At Sarnoff Corporation in Princeton, NJ, and Columbia University, researchers have succeeded in operating circuits at 100 megahertz — as much as a hundred times faster than previous ones on plastic. The Sarnoff/Columbia advance could lead to displays measuring three meters or more diagonally that can also be rolled up and easily transported. 10-100 times …

New tool – grows carbon nanotubes at room temperature

CEVP has developed a fabrication tool to commercialise the revolutionary low temperature carbon nanotube growth process developed by the University of Surrey’s (UniS) Advanced Technology Institute (ATI). The new tool – NanoGrowth – is currently being trialled and characterised by UniS, and the two partners anticipate releasing the technology for commercial use in March 2006. …

Polyyne : background info on triple bonded carbon

Polyyne-containing carbon has attracted attention as a new type of carbon material for its unique triple-bond linear structure. It is recognized not only as a new carbon but also as a precursor for the preparation of new types of carbon materials. The polyyne-containing carbon was prepared by electrochemical reduction of a polytetrafluoroethylene (PTFE) film with …

Problems with MIT Technology Review article and unproductive attacks of opposing views

Here is a list of the problems with an article by David Rotman called Fictional Science which attacks supporters and those that work towards living forever or self-replicating nanobots: 1. An example of applying logic to parts of the article. Rotman disparage the opinion of “non-researchers” and claim that they should not be given attention. …

Targeted self-assembly of molecules

Targeted self-assembly could vastly expand the range of structures that could be created from nano-particles. Torquato and colleagues have published a paper in the Nov. 25 issue of Physical Review Letters, the leading physics journal, outlining a mathematical approach that would enable them to produce desired configurations of nanoparticles by manipulating the manner in which …
