SCIENTISTS USE VIRUS TO CREATE NANO BUILDING BLOCKS

Absolutely amazing! This may be the precurser to building a nano-manufacturing device which could build ANYTHING!
UK scientists from Norwich have used a plant virus to create nanotechnology building blocks.

The virus, which infects black-eyed peas, was employed as a "scaffold" on to which other chemicals were attached.

By linking iron-containing compounds to the virus's surface, the John Innes Centre team was able to create electronically active nanoparticles.

The researchers tell the journal Small that their work could be used in the future to make tiny electrical devices.

The work is yet another example of how scientists are now trying to engineer objects on the scale of atoms and molecules.

At the nanoscale, materials can be "tuned" to display unusual properties that could be exploited to build faster, lighter, stronger and more efficient devices and systems.
