Using gold particles to make the invisible visible

Gold nanoparticles give us a better understanding of enzymes and other molecules. Biswajit Pradhan, Ph.D. candidate at the Leiden Institute of Physics, uses gold nanorods to study individual molecules that would be challenging ...

A dash of gold improves microlasers

Gold. The word brings to mind wedding rings, buried treasure and California in the 1840's. But when gold is reduced to 1/100,000 the size of a human hair, it takes on an entirely new personality.

Killing cancer in the heat of the moment

Mineko Kengaku, Tatsuya Murakami, and their colleagues from Kyoto University's Institute for Integrated Cell-Material Sciences (iCeMS) have developed a new method that modifies the surface of nanorods, making them more efficient ...

Tracking the protein patrollers

A nanoprobe developed by biophysicists at NC State could allow researchers to trace the movements of different proteins along DNA – without the drawbacks of current methods.

Stretchable hologram can switch between multiple images

The possibility of sending and receiving holographic messages has long tantalized sci-fi fans. Although we're not there yet, scientists have now created holograms that can change from one image to another as the materials ...
