Nanotechnology-enabled pill signals it has been swallowed

Seeking a way to confirm that patients have taken their medication, University of Florida engineering researchers have added a tiny microchip and digestible antenna to a standard pill capsule. The prototype is intended to pave the way for mass-produced pills that, when ingested, automatically alert doctors, loved ones or scientists working with patients in clinical drug trials.

Spray-on manufacturing of transistors with organic semiconductors

A multidisciplinary research team at the National Institute of Standards and Technology (NIST) has found that an organic semiconductor may be a viable candidate for creating large-area electronics, such as solar cells and displays that can be sprayed onto a surface as easily as paint.

Atomic-scale tug-of-war - how to pull a chain of atoms apart

How hard do you have to pull on a single atom of - let's say - gold to detach it from the end of a chain of like atoms? It's a measure of the astonishing progress in nanotechnology that questions that once would have interested only physicists or chemists are now being asked by engineers.

From a classical laser to a 'quantum laser'

Rainer Blatt's and Piet Schmidt's research team from the University of Innsbruck have successfully realized a single-atom laser, which shows the properties of a classical laser as well as quantum mechanical properties of the atom-photon interaction.
