Cooling with light

ETH researchers have cooled a nanoparticle to a record low temperature, thanks to a sophisticated experimental set-up that uses scattered laser light for cooling. Until now, no one has ever cooled a nanoparticle to such ...

Lipid vesicles transmit luminous or electrical signals

Liposomes are small spherical vesicles with walls comprising two layers of lipids and containing an aqueous core. These artificial structures have been developed for drug delivery or as carriers of active substances in cosmetic ...

Small and bright—what nanophotonics means for you

Twenty fifteen was UNESCO's International Year of Light and Light based Technologies. It was a celebration of past milestones in optics and photonics and a look forward into its future.

Five ways nanotechnology is securing your future

The past 70 years have seen the way we live and work transformed by two tiny inventions. The electronic transistor and the microchip are what make all modern electronics possible, and since their development in the 1940s ...

3-D images of tiny objects down to 25 nanometres

Scientists at the Paul Scherrer Institute and ETH Zurich (Switzerland) have created 3D images of tiny objects showing details down to 25 nanometres. In addition to the shape, the scientists determined how particular chemical ...

New holographic process uses image-stabilized X-ray camera

A team headed by Stefan Eisebitt has developed a new X-ray holography method that will enable snap-shots of dynamic processes at highest spatial resolution. The efficiency of the new method is based on a X-ray focussing optics ...
