Machine learning may improve molecular design for nanotechnology

A set of machine learning programs can now predict properties of small organic molecules as accurately as can calculations based upon the Schrödinger equation, but in milliseconds rather than hours.

Nanotechnology, DNA sequencing, and personalized medicine

Artist’s conception of a nanopore drilled into a layer of graphene to speed up DNA sequencing. One of the greatest promises of near-term nanotechnoloogy is cheaper DNA sequencing to speed the development of personalized medicine. There are not only genetic differences between different patients, but also genetic differences between, for example, different cancers of the… Continue reading Nanotechnology, DNA sequencing, and personalized medicine

Atomically-precise positioning of a single atom transistor-VIDEO

Researchers in Australia and the US have demonstrated a working transistor by placing of single atom of phosphorous with atomic precision between gates made of wires only a few phosphorous atoms wide. This demonstration points to possibly extending current computer technology to the atomic scale.

Graphene heterostructures may lead to graphene-based computer chips

A field-effect tunneling transistor comprising a vertical heterostructure of atomically thin layers of graphene and boron nitride or molybdenum disulfide may pave the way for computer chips based on graphene nanotechnology.

Current nanotechnology too cool to ignore

ideo of a superhydrophobic spray-on coating shows chocolate syrup shooting off a white shoe leaving it spotless.

DNA motor navigates network of DNA tracks

Scientists at Kyoto University and the University of Oxford have combined DNA origami and DNA motors to take another step toward programmed artificial molecular assembly lines.

Panel recommends research to manage health and environmental risks of nanomaterials

A National Academy of Sciences panel has recommended a four-part research effort focused on preventing and managing any potential health and environmental risks of nanomaterials.

Crowd-sourced protein design a promising path to advanced nanotechnology

Foldit game players have again out-performed scientists in protein design, this time improving the design of a protein designed from scratch to catalyze Diels-Alder cycloadditions.

Foresight co-founder among panelists discussing role of technology in human existence

Human life after advanced nanotechnology has been developed will be fundamentally different from life up until that point.

Magnetic storage systems shrink from a million atoms per bit to twelve

An array of 96 iron atoms on a copper nitride surface, assembled using an STM and used to write a byte, demonstrates how small magnetic storage could shrink and may lead to novel nanomaterials for quantum computers.
