    Gold does not readily lend itself to being turned into long, thin threads. But researchers at Linköping University in Sweden have now managed to create gold nanowires and develop soft electrodes that can be connected to the nervous system. The electrodes are soft as nerves, stretchable and electrically conductive, and are projected to last for a long time in the body.

    Some people have a “heart of gold,” so why not “nerves of gold”? In the future, it may be possible to use this precious metal in soft interfaces to connect electronics to the ...

    Dose of Vitamin C helps Gold Nanowires Grow

    Gold nanowires grown in the Rice University lab of chemist Eugene Zubarev promise to provide tunable plasmonic properties for optical and electronic applications. The wires can be controllably grown from nanorods, or reduced.

    Scientists discover a method to turn stubby gold nanorods into gold nanowires of impressive length. The metal wires could be valuable for sensing, diagnostic, imaging and therapeutic applications. A boost of vitamin C helped Rice University scientists turn small gold nanorods into fine gold nanowires.

    Common, mild ascorbic acid is the not-so-secret sauce that helped the Rice lab of chemist Eugene Zubarev grow pure batches of nanowires from stumpy nanorods without the drawbacks of previous techniques.

    “There’s n...
