Scientific Image - Gold Nanoshells (optical microscope)

To create this optical 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: Optical microscope

Battling Cancer with Nanotechnology Video

"Battling Cancer with Nanotechnology" is a 6-minute video that shares the research of Mauro Ferrari, a leading pioneer in the field of cancer nanomedicine. A visionary optimist, Ferrari applied his mathematical physics and engineering skills to medicine and is determined to overcome every obstacle on the way to conquering cancer's cruel reign. Dr. Ferrari's research is one of several new nanomedicine-based approaches to cancer treatment that is explored in the Nanomedicine Explorer kiosk, website and DVD (also on

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.”

Nanomedicine Explorer Website and DVD

The Nanomedicine Explorer is an interactive, bilingual, multimedia program and website. Visitors can explore a variety of research areas in cancer nanomedicine through vivid animations and video story-telling up close with a diverse group of researchers. Interactive features include games, polls, and options to dig deeper into the material. Fully bilingual English/Espanol. The multimedia package on DVD can also be loaded into any computer display or custom-built cabinet to augment existing health, medicine,and nanotechnology exhibits.
