QR codes, those goofy black-and-white arrangements of digital information, could help secure bank notes. Scientists just showed that they could print an invisible QR code made of a high-tech ink containing fluorescent nanoparticles, layering it on in a thin, 50 micron layer on a sheet of paper. The printed patch...

Manipulating nanoparticles with an electron tractor beam

www.extremetech.com
A group of scientists from Lawrence Berkeley National Laboratory and the National University of Singapore recently had their way with a 10nm particle made of gold. They used an electron beam, produced by a Transmission Electron Microscope (TEM) to tractor the nanoparticle with a piconewton force, enabling them to move...

Earthworm guts become factory for nanoparticles

arstechnica.com
Enlarge / Meet the latest quantum dot assembly factory. Colorado State Quantum dots are nanoscale-sized pieces of semiconductor. Their small size ensures that quantum effects, like the Pauli exclusion principle, influence the behavior of electrons within them. This gives the dots properties that a bulk material with the same...
