Nano QR: Is this the smallest QR code in the world?

Is this the smallest QR code in the world? With each cell just 1 micron wide (a human hair is 40-300 microns), we think it just might be.

Dr Colm Faulkner at CRANN etched the NanoQR on material just three atoms thick using a Focused Ion Beam microscope, which acts like an atomic chisel. This code was patterened into a thin film calld a magnetic tunnel junciton. This material is from Prof JMD Coey's research group and is made up of layers of mostly metals, some only 3 atoms thick! The scientists at CRANN pattern these thin films to investigate future data storage and logic processing technologies. This type of research is leading to lighter, smaller consumer electronics and in principle PC's that have no boot-up time.With no smartphones that we know of currently featuring an electron microscope, they also took this image of it using an electron beam for us to share.

Visitors will have the chance to explore how cutting edge developments in nanotechnology could transform everything from electronics to medicine and clothing at ‘NANOLAB’ in September 2012 - part of the Science Gallery’s 2012 programme, which launched today.

2012 is a big year for us. Dublin will take up its tenure as European City of Science 2012, host over 5,000 scientists as part of Euroscience Open Forum, and we will welcome our millionth visitor since opening in 2008. In addition to NANOLAB, we have an exciting line-up of exhibition, events and workshops planned.
