Tiny treasure: The future of nano-gold Video

Lumps of gold moulded into rings, coins and ingots have been highly prized for millennia. But recently, scientists have realised that tiny pieces of this precious metal – far too small to be seen by the naked eye - could also become a valued commodity. In labs around the world, gold nanoparticles are being tested as components in technology and medicines. See how gold could be used to kill cancer cells, improve the efficiency of solar cells and catalyse chemical reactions. (5:17 min)

Exploring Materials - Stained-Glass Windows

"Exploring Materials - Stained-Glass Windows" is a hands-on activity in which visitors use contact paper and colored tissue paper to create a "stained-glass" window. They learn that real stained-glass windows use nanoparticles to create some of the colors in the glass.

"Explore Science - Zoom info Nano Stained Glass Art" (2016) version designed for groups and community outreach.

Online Brown-Bag: The International Year of Light 2015 - What's Nano about Light? (Recorded)

This is a recording of a NISE Network online brown-bag conversation held in December 2014 about the International Year of Light. In 2013, the United Nations proclaimed 2015 as the International Year of Light (IYL). More than 100 organizations from more than 85 countries are participating in IYL. During this conversation we discussed scientific organizations that would make great partners for IYL events, shared light-related activities and videos developed by the NISE Network, and talked about the science behind some of those activities.

Scientific Image - Gold Nanoshells (SEM)

To create this scanning electron microscope image, gold nanoshells were dispersed in a drop of water which then dried on a glass microscope slide. The colors are due to selective scattering of light by nanoscale particles.

Gold Nanoshells have a variety of uses in nanotechnology, and especially in biomedical applications. Nanoshells like these may play important roles in new kinds of cancer treatments, disease detection, and imaging techniques.

• SIZE: These gold nanoshells are each about 120 nm in diameter.

• IMAGING TOOL: Scanning electron microscope

Stealth Imaging with Iron Nanoparticles Video

"Stealth Imaging with Iron Nanoparticles" is an 8-minute video that tells the research story of Ralph Weissleder and Mukesh Harisinghani, who collaborated on the design of a clinical trial to determine if an injection of specially-designed iron-oxide nanoparticles could enhance a diagnostic image produced by an MRI machine to the extent that the spread of cancer could be accurately assessed. At least in the case of prostate cancer, as Dr. Weissleder tells our producer in this story, “The results were stunning.” Dr. Weissleder and Dr. Harisinghani's experimental cancer...
