It has not been tested experimentally yet, but if a proposal to use graphene as a nanotech method to sequence DNA very rapidly and inexpensively pans out, the “wonder material” of nanotechnology could find yet another use.

British scientists are investigating telescoping carbon nanotubes as a nanotech replacement for current computer memory technologies.
Recently announced results of a US national survey on nanotech applications for “human enhancement” show widespread public support for enhancements seen as promising an improvement in human health, but little support for other uses.
The report concludes that nanotech products are coming to market without adequate tests for safety based upon the unique properties of the nanomaterials.
Today we have a nanotech nod to last week’s historic election for US President and an example of the artistic possibilities of nanotechnology.
Nanotech membranes made of nanoporous alumina coated with diamond-like carbon films promise to minimize problems with medical implants.
The publication of a method to mass produce graphene has opened the way to further study of this remarkable nanomaterial.
A patch consisting of three layers of polymers can be loaded with nanoparticles and attached to living cells to give them nanotech backpacks.
Re-engineering a simple nanotech device to make it more functional, Chinese scientists have developed an improved DNA tweezers that is able to capture, hold, and release a target molecule in a controlled manner.
Robert A. Freitas Jr. brings to our attention a major step on the road to advanced nanotech, published a couple weeks ago in Science (abstract). He writes: This paper reports purely mechanical-based covalent bond-making and bond-breaking (true mechanosynthesis) involving atom by atom substitution of silicon (Si) atoms for tin (Sn) atoms in an Sn monolayer… Continue reading Mechanosynthesis with AFM as a step toward advanced nanotechnology
