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
